-Garage is a lightweight S3-compatible distributed object store, with the following goals:
+Garage is an S3-compatible distributed object storage service
+designed for self-hosting at a small-to-medium scale.
 
-- As self-contained as possible
-- Easy to set up
-- Highly resilient to network failures, network latency, disk failures, sysadmin failures
-- Relatively simple
-- Made for multi-datacenter deployments
+Garage is designed for storage clusters composed of nodes running
+at different physical locations,
+in order to easily provide a storage service that replicates data at these different
+locations and stays available even when some servers are unreachable.
+Garage also focuses on being lightweight, easy to operate, and highly resilient to
+machine failures.
 
-Non-goals include:
+Garage is built by [Deuxfleurs](https://deuxfleurs.fr),
+an experimental small-scale self hosted service provider,
+which has been using it in production since its first release in 2020.
 
-- Extremely high performance
-- Complete implementation of the S3 API
-- Erasure coding (our replication model is simply to copy the data as is on several nodes, in different datacenters if possible)
+Learn more on our dedicated documentation pages:
 
-Our main use case is to provide a distributed storage layer for small-scale self hosted services such as [Deuxfleurs](https://deuxfleurs.fr).

+Garage has many API that you can rely on to build complex applications.
+In this section, we reference the existing SDKs and give some code examples.
+
+
+## ⚠️ DISCLAIMER
+
+**K2V AND ADMIN SDK ARE TECHNICAL PREVIEWS**. The following limitations apply:
+  - The API is not complete, some actions are possible only through the `garage` binary
+  - The underlying admin API is not yet stable nor complete, it can breaks at any time
+  - The generator configuration is currently tweaked, the library might break at any time due to a generator change
+  - Because the API and the library are not stable, none of them are published in a package manager (npm, pypi, etc.)
+  - This code has not been extensively tested, some things might not work (please report!)
+
+To have the best experience possible, please consider:
+  - Make sure that the version of the library you are using is pinned (`go.sum`, `package-lock.json`, `requirements.txt`).
+  - Before upgrading your Garage cluster, make sure that you can find a version of this SDK that works with your targeted version and that you are able to update your own code to work with this new version of the library.
+  - Join our Matrix channel at `#garage:deuxfleurs.fr`, say that you are interested by this SDK, and report any friction.
+  - If stability is critical, mirror this repository on your own infrastructure, regenerate the SDKs and upgrade them at your own pace.
+
+
+## About the APIs
+
+Code can interact with Garage through 3 different APIs: S3, K2V, and Admin.
+Each of them has a specific scope.
+
+### S3
+
+De-facto standard, introduced by Amazon, designed to store blobs of data.
+
+### K2V
+
+A simple database API similar to RiakKV or DynamoDB.
+Think a key value store with some additional operations.
+Its design is inspired by Distributed Hash Tables (DHT).
+
+More information:
+  - [In the reference manual](@/documentation/reference-manual/k2v.md)
+
+
+### Administration
+
+Garage operations can also be automated through a REST API.
+We are currently building this SDK for [Python](@/documentation/build/python.md#admin-api), [Javascript](@/documentation/build/javascript.md#administration) and [Golang](@/documentation/build/golang.md#administration).
+

+## Admin API
+
+You need at least Python 3.6, pip, and setuptools.
+Because the python package is in a subfolder, the command is a bit more complicated than usual:
+
+```bash
+pip3 install --user 'git+https://git.deuxfleurs.fr/garage-sdk/garage-admin-sdk-python'
+```
+
+Now, let imagine you have a fresh Garage instance running on localhost, with the admin API configured on port 3903 with the bearer `s3cr3t`:
+
+```python
+import garage_admin_sdk
+from garage_admin_sdk.apis import *
+from garage_admin_sdk.models import *
+
+configuration = garage_admin_sdk.Configuration(
+  host = "http://localhost:3903/v0",
+  access_token = "s3cr3t"
+)
+
+# Init APIs
+api = garage_admin_sdk.ApiClient(configuration)
+nodes, layout, keys, buckets = NodesApi(api), LayoutApi(api), KeyApi(api), BucketApi(api)
+
+# Display some info on the node
+status = nodes.get_nodes()
+print(f"running garage {status.garage_version}, node_id {status.node}")
+
+# Change layout of this node

+    capacity = 1,
+    tags = [ "dev" ],
+  )
+})
+layout.apply_layout(LayoutVersion(
+  version = current.version + 1
+))
+
+# Create key, allow it to create buckets
+kinfo = keys.add_key(AddKeyRequest(name="openapi"))
+

 ## Mastodon
 
-https://docs.joinmastodon.org/admin/config/#cdn
+Mastodon natively supports the S3 protocol to store media files, and it works out-of-the-box with Garage.
+You will need to expose your Garage bucket as a website: that way, media files will be served directly from Garage.
+
+### Performance considerations
+
+Mastodon tends to store many small objects over time: expect hundreds of thousands of objects,
+with average object size ranging from 50 KB to 150 KB.
+
+As such, your Garage cluster should be configured appropriately for good performance:
+
+- use Garage v0.8.0 or higher with the [LMDB database engine](@documentation/reference-manual/configuration.md#db-engine-since-v0-8-0).
+  With the default Sled database engine, your database could quickly end up taking tens of GB of disk space.
+- the Garage database should be stored on a SSD
+
+### Creating your bucket
+
+This is the usual Garage setup:
+
+```bash
+garage key new --name mastodon-key
+garage bucket create mastodon-data
+garage bucket allow mastodon-data --read --write --key mastodon-key
+```
+
+Note the Key ID and Secret Key.
+
+### Exposing your bucket as a website
+
+Create a DNS name to serve your media files, such as `my-social-media.mydomain.tld`.
+This name will be publicly exposed to the users of your Mastodon instance: they
+will load images directly from this DNS name.
+
+As [documented here](@/documentation/cookbook/exposing-websites.md),
+add this DNS name as alias to your bucket, and expose it as a website:
+
+```bash
+garage bucket alias mastodon-data my-social-media.mydomain.tld
+garage bucket website --allow mastodon-data
+```
+
+Then you will likely need to [setup a reverse proxy](@/documentation/cookbook/reverse-proxy.md)
+in front of it to serve your media files over HTTPS.
+
+### Cleaning up old media files before migration
+
+Mastodon instance quickly accumulate a lot of media files from the federation.
+Most of them are not strictly necessary because they can be fetched again from
+other servers.  As such, it is highly recommended to clean them up before
+migration, this will greatly reduce the migration time.
+
+From the [official Mastodon documentation](https://docs.joinmastodon.org/admin/tootctl/#media):
+
+```bash
+$ RAILS_ENV=production bin/tootctl media remove --days 3
+$ RAILS_ENV=production bin/tootctl media remove-orphans
+$ RAILS_ENV=production bin/tootctl preview_cards remove --days 15
+```
+
+Here is a typical disk usage for a small but multi-year instance after cleanup:
+
+```bash
+$ RAILS_ENV=production bin/tootctl media usage
+Attachments:	5.67 GB (1.14 GB local)
+Custom emoji:	295 MB (0 Bytes local)
+Preview cards:	154 MB
+Avatars:	3.77 GB (127 KB local)
+Headers:	8.72 GB (242 KB local)
+Backups:	0 Bytes
+Imports:	1.7 KB
+Settings:	0 Bytes
+```
+
+Unfortunately, [old avatars and headers cannot currently be cleaned up](https://github.com/mastodon/mastodon/issues/9567).
+
+### Migrating your data
+
+Data migration should be done with an efficient S3 client.
+The [minio client](@documentation/connect/cli.md#minio-client) is a good choice
+thanks to its mirror mode:
+
+```bash
+mc mirror ./public/system/ garage/mastodon-data
+```
+
+Here is a typical bucket usage after all data has been migrated:
+
+```bash
+$ garage bucket info mastodon-data
+
+Size: 20.3 GiB (21.8 GB)
+Objects: 175968
+```
+
+### Configuring Mastodon
+
+In your `.env.production` configuration file:
+
+```bash
+S3_ENABLED=true
+# Internal access to Garage
+S3_ENDPOINT=http://my-garage-instance.mydomain.tld:3900
+S3_REGION=garage
+S3_BUCKET=mastodon-data
+# Change this (Key ID and Secret Key of your Garage key)
+AWS_ACCESS_KEY_ID=GKe88df__CHANGETHIS__c5145
+AWS_SECRET_ACCESS_KEY=a2f7__CHANGETHIS__77fcfcf7a58f47a4aa4431f2e675c56da37821a1070000
+# What name gets exposed to users (HTTPS is implicit)
+S3_ALIAS_HOST=my-social-media.mydomain.tld
+```
+
+For more details, see the [reference Mastodon documentation](https://docs.joinmastodon.org/admin/config/#cdn).
+
+Restart all Mastodon services and everything should now be using Garage!
+You can check the URLs of images in the Mastodon web client, they should start
+with `https://my-social-media.mydomain.tld`.
+
+### Last migration sync
+
+After Mastodon is successfully using Garage, you can run a last sync from the local filesystem to Garage:
+
+```bash
+mc mirror --newer-than "3h" ./public/system/ garage/mastodon-data
+```

+Backups are essential for disaster recovery but they are not trivial to manage.
+Using Garage as your backup target will enable you to scale your storage as needed while ensuring high availability.
+
+## Borg Backup
+
+Borg Backup is very popular among the backup tools but it is not yet compatible with the S3 API.
+We recommend using any other tool listed in this guide because they are all compatible with the S3 API.
+If you still want to use Borg, you can use it with `rclone mount`.
+
+
+
+## Restic
+
+Create your key and bucket:
+
+```bash
+garage key new my-key
+garage bucket create backup
+garage bucket allow backup --read --write --key my-key
+```
+
+Then register your Key ID and Secret key in your environment:
+
+```bash
+export AWS_ACCESS_KEY_ID=GKxxx
+export AWS_SECRET_ACCESS_KEY=xxxx
+```
+
+Configure restic from environment too:
+
+```bash
+export RESTIC_REPOSITORY="s3:http://localhost:3900/backups"
+
+echo "Generated password (save it safely): $(openssl rand -base64 32)"
+export RESTIC_PASSWORD=xxx # copy paste your generated password here
+```
+
+Do not forget to save your password safely (in your password manager or print it). It will be needed to decrypt your backups.
+
+Now you can use restic:
+
+```bash
+# Initialize the bucket, must be run once
+restic init
+
+# Backup your PostgreSQL database
+# (We suppose your PostgreSQL daemon is stopped for all commands)
+restic backup /var/lib/postgresql
+
+# Show backup history
+restic snapshots
+
+# Backup again your PostgreSQL database, it will be faster as only changes will be uploaded
+restic backup /var/lib/postgresql
+
+# Show backup history (again)
+restic snapshots
+
+# Restore a backup
+# (79766175 is the ID of the snapshot you want to restore)
+mv /var/lib/postgresql /var/lib/postgresql.broken
+restic restore 79766175 --target /var/lib/postgresql
+```
+
+Restic has way more features than the ones presented here.
+You can discover all of them by accessing its documentation from the link below.

+## Duplicati
+
+*External links:* [Duplicati Documentation > Storage Providers](https://duplicati.readthedocs.io/en/latest/05-storage-providers/#s3-compatible)

+Bucket name: bucket-name
+Bucket create region: Custom region value (garage) # Or as you've specified in garage.toml
+AWS Access ID: Key ID from "garage key info key-name"
+AWS Access Key: Secret key from "garage key info key-name"
+Client Library to use: Minio SDK
+```
+
+Click `Test connection` and then no when asked `The bucket name should start with your username, prepend automatically?`. Then it should say `Connection worked!`.

+
+## kopia
+
+*External links:* [Kopia Documentation > Repositories](https://kopia.io/docs/repositories/#amazon-s3)
+
+To create the Kopia repository, you need to specify the region, the HTTP(S) endpoint, the bucket name and the access keys.
+For instance, if you have an instance of garage running on `https://garage.example.com`:
+
+```
+kopia repository create s3 --region=garage --bucket=mybackups --access-key=KEY_ID --secret-access-key=SECRET_KEY --endpoint=garage.example.com
+```
+
+Or if you have an instance running on localhost, without TLS:
+
+```
+kopia repository create s3 --region=garage --bucket=mybackups --access-key=KEY_ID --secret-access-key=SECRET_KEY --endpoint=localhost:3900 --disable-tls
+```
+
+After the repository has been created, check that everything works as expected:
+
+```
+kopia repository validate-provider
+```
+
+You can then run all the standard kopia commands: `kopia snapshot create`, `kopia mount`...
+Everything should work out-of-the-box.

+## Configuring a bucket for website access
+
+There are three methods to expose buckets as website:
+
+1. using the PutBucketWebsite S3 API call, which is allowed for access keys that have the owner permission bit set
+
+2. from the Garage CLI, by an adminstrator of the cluster
+
+3. using the Garage administration API
+
+The `PutBucketWebsite` API endpoint [is documented](https://docs.aws.amazon.com/AmazonS3/latest/API/API_PutBucketWebsite.html) in the official AWS docs.
+This endpoint can also be called [using `aws s3api`](https://docs.aws.amazon.com/cli/latest/reference/s3api/put-bucket-website.html) on the command line.
+The website configuration supported by Garage is only a subset of the possibilities on Amazon S3: redirections are not supported, only the index document and error document can be specified.
+
+If you want to expose your bucket as a website from the CLI, use this simple command:
+
+```bash
+garage bucket website --allow my-website
+```
+
+Now it will be **publicly** exposed on the web endpoint (by default listening on port 3902).
+
+## How exposed websites work
+
+Our website serving logic is as follow:
+
+  - Supports only static websites (no support for PHP or other languages)
+  - Does not support directory listing
+  - The index file is defined per-bucket and can be specified in the `PutBucketWebsite` call
+     or on the CLI using the `--index-document` parameter (default: `index.html`)
+  - A custom error document for 404 errors can be specified in the `PutBucketWebsite` call
+    or on the CLI using the `--error-document` parameter
+
+Now we need to infer the URL of your website through your bucket name.
+Let assume:
+  - we set `root_domain = ".web.example.com"` in `garage.toml` ([ref](@/documentation/reference-manual/configuration.md#root_domain))
+  - our bucket name is `garagehq.deuxfleurs.fr`.
+
+Our bucket will be served if the Host field matches one of these 2 values (the port is ignored):
+
+  - `garagehq.deuxfleurs.fr.web.example.com`: you can dedicate a subdomain to your users (here `web.example.com`).
+
+  - `garagehq.deuxfleurs.fr`: your users can bring their own domain name, they just need to point them to your Garage cluster.
+
+You can try this logic locally, without configuring any DNS, thanks to `curl`:
+
+```bash
+# prepare your test
+echo hello world > /tmp/index.html
+mc cp /tmp/index.html garage/garagehq.deuxfleurs.fr
+
+curl -H 'Host: garagehq.deuxfleurs.fr' http://localhost:3902
+# should print "hello world"
+
+curl -H 'Host: garagehq.deuxfleurs.fr.web.example.com' http://localhost:3902
+# should also print "hello world"
+```
+
+Now that you understand how website logic works on Garage, you can:
+
+ - make the website endpoint listens on port 80 (instead of 3902)
+ - use iptables to redirect the port 80 to the port 3902:  
+   `iptables -t nat -A PREROUTING -p tcp -dport 80 -j REDIRECT -to-port 3902`
+ - or configure a [reverse proxy](@/documentation/cookbook/reverse-proxy.md) in front of Garage to add TLS (HTTPS), CORS support, etc.
+
+You can also take a look at [Website Integration](@/documentation/connect/websites.md) to see how you can add Garage to your workflow.

+
+
+Garage is a standard Rust project.  First, you need `rust` and `cargo`.  For instance on Debian:
+
+```bash
+sudo apt-get update
+sudo apt-get install -y rustc cargo
+```
+
+You can also use [Rustup](https://rustup.rs/) to setup a Rust toolchain easily.
+
+In addition, you will need a full C toolchain. On Debian-based distributions, it can be installed as follows:
+
+```bash
+sudo apt-get update
+sudo apt-get install build-essential
+```
+
+## Building from source from the Gitea repository
+
+The primary location for Garage's source code is the
+[Gitea repository](https://git.deuxfleurs.fr/Deuxfleurs/garage),
+which contains all of the released versions as well as the code
+for the developpement of the next version.
+
+Clone the repository and enter it as follows:
+
+```bash
+git clone https://git.deuxfleurs.fr/Deuxfleurs/garage.git
+cd garage
+```
+
+If you wish to build a specific version of Garage, check out the corresponding tag. For instance:
+
+```bash
+git tag  				# List available tags
+git checkout v0.8.0		# Change v0.8.0 with the version you wish to build
+```
+
+Otherwise you will be building a developpement build from the `main` branch
+that includes all of the changes to be released in the next version.
+Be careful that such a build might be unstable or contain bugs,
+and could be incompatible with nodes that run stable versions of Garage.
+
+Finally, build Garage with the following command:
+
+```bash
+cargo build --release
+```
+
+The binary built this way can now be found in `target/release/garage`.
+You may simply copy this binary to somewhere in your `$PATH` in order to
+have the `garage` command available in your shell, for instance:
+
+```bash
+sudo cp target/release/garage /usr/local/bin/garage
+```
+
+If you are planning to develop Garage,
+you might be interested in producing debug builds, which compile faster but run slower:
+this can be done by removing the `--release` flag, and the resulting build can then
+be found in `target/debug/garage`.
+
+## List of available Cargo feature flags
+
+Garage supports a number of compilation options in the form of Cargo feature flags,
+which can be used to provide builds adapted to your system and your use case.
+To produce a build with a given set of features, invoke the `cargo build` command
+as follows:
+
+```bash
+# This will build the default feature set plus feature1, feature2 and feature3
+cargo build --release --features feature1,feature2,feature3
+# This will build ONLY feature1, feature2 and feature3
+cargo build --release --no-default-features \
+            --features feature1,feature2,feature3
+```
+
+The following feature flags are available in v0.8.0:
+
+| Feature flag | Enabled | Description |
+| ------------ | ------- | ----------- |
+| `bundled-libs` | *by default* | Use bundled version of sqlite3, zstd, lmdb and libsodium |
+| `system-libs` | optional | Use system version of sqlite3, zstd, lmdb and libsodium<br>if available (exclusive with `bundled-libs`, build using<br>`cargo build --no-default-features --features system-libs`) |
+| `k2v` | optional | Enable the experimental K2V API (if used, all nodes on your<br>Garage cluster must have it enabled as well) |
+| `kubernetes-discovery` | optional | Enable automatic registration and discovery<br>of cluster nodes through the Kubernetes API |
+| `metrics` | *by default* | Enable collection of metrics in Prometheus format on the admin API |
+| `telemetry-otlp` | optional | Enable collection of execution traces using OpenTelemetry |
+| `sled` | *by default* | Enable using Sled to store Garage's metadata |
+| `lmdb` | optional | Enable using LMDB to store Garage's metadata |
+| `sqlite` | optional | Enable using Sqlite3 to store Garage's metadata |

+cd garage/scripts/helm
+```
+
+Deploy with default options:
+
+```bash

+
+After deploying, cluster layout must be configured manually as described in [Creating a cluster layout](@/documentation/quick-start/_index.md#creating-a-cluster-layout). Use the following command to access garage CLI:
+
+```bash
+kubectl exec --stdin --tty -n garage garage-0 -- ./garage status

+Garage exposes some internal metrics in the Prometheus data format.
+This page explains how to exploit these metrics.
+
+## Setting up monitoring
+
+### Enabling the Admin API endpoint
+
+If you have not already enabled the [administration API endpoint](@/documentation/reference-manual/admin-api.md), do so by adding the following lines to your configuration file:
+
+```toml
+[admin]
+api_bind_addr = "0.0.0.0:3903"
+```
+
+This will allow anyone to scrape Prometheus metrics by fetching
+`http://localhost:3093/metrics`. If you want to restrict access
+to the exported metrics, set the `metrics_token` configuration value
+to a bearer token to be used when fetching the metrics endpoint.
+
+### Setting up Prometheus and Grafana
+
+Add a scrape config to your Prometheus daemon to scrape metrics from
+all of your nodes:
+
+```yaml
+scrape_configs:
+  - job_name: 'garage'
+    static_configs:
+      - targets:
+        - 'node1.mycluster:3903'
+        - 'node2.mycluster:3903'
+        - 'node3.mycluster:3903'
+```
+
+If you have set a metrics token in your Garage configuration file,
+add the following lines in your Prometheus scrape config:
+
+```yaml
+    authorization:
+      type: Bearer
+      credentials: 'your metrics token'
+```
+
+To visualize the scraped data in Grafana,
+you can either import our [Grafana dashboard for Garage](https://git.deuxfleurs.fr/Deuxfleurs/garage/raw/branch/main/script/telemetry/grafana-garage-dashboard-prometheus.json)
+or make your own.
+We detail below the list of exposed metrics and their meaning.

+Note that Garage will **always** store the three copies of your data on nodes at different
+locations. This means that in the case of this small example, the available capacity
+of the cluster is in fact only 1.5 TB, because nodes in Brussels can't store more than that.
+This also means that nodes in Paris and London will be under-utilized.
+To make better use of the available hardware, you should ensure that the capacity
+available in the different locations of your cluster is roughly the same.
+For instance, here, the Mercury node could be moved to Brussels; this would allow the cluster
+to store 2 TB of data in total.
 
+### Best practices
+
+- If you have fast dedicated networking between all your nodes, and are planing to store
+  very large files, bump the `block_size` configuration parameter to 10 MB
+  (`block_size = 10485760`).
+
+- Garage stores its files in two locations: it uses a metadata directory to store frequently-accessed
+  small metadata items, and a data directory to store data blocks of uploaded objects.
+  Ideally, the metadata directory would be stored on an SSD (smaller but faster),
+  and the data directory would be stored on an HDD (larger but slower).
+
+- For the data directory, Garage already does checksumming and integrity verification,
+  so there is no need to use a filesystem such as BTRFS or ZFS that does it.
+  We recommend using XFS for the data partition, as it has the best performance.
+  EXT4 is not recommended as it has more strict limitations on the number of inodes,
+  which might cause issues with Garage when large numbers of objects are stored.
+
+- If you only have an HDD and no SSD, it's fine to put your metadata alongside the data
+  on the same drive. Having lots of RAM for your kernel to cache the metadata will
+  help a lot with performance.  Make sure to use the LMDB database engine,
+  instead of Sled, which suffers from quite bad performance degradation on HDDs.
+  Sled is still the default for legacy reasons, but is not recommended anymore.
+
+- For the metadata storage, Garage does not do checksumming and integrity
+  verification on its own. If you are afraid of bitrot/data corruption,
+  put your metadata directory on a BTRFS partition. Otherwise, just use regular
+  EXT4 or XFS.
+
+- Having a single server with several storage drives is currently not very well
+  supported in Garage ([#218](https://git.deuxfleurs.fr/Deuxfleurs/garage/issues/218)).
+  For an easy setup, just put all your drives in a RAID0 or a ZFS RAIDZ array.
+  If you're adventurous, you can try to format each of your disk as
+  a separate XFS partition, and then run one `garage` daemon per disk drive,
+  or use something like [`mergerfs`](https://github.com/trapexit/mergerfs) to merge
+  all your disks in a single union filesystem that spreads load over them.

@@ -0,0 +1,308 @@
++++
+title = "Configuring a reverse proxy"
+weight = 30
++++
+
+The main reason to add a reverse proxy in front of Garage is to provide TLS to your users and serve multiple web services on port 443.
+
+In production you will likely need your certificates signed by a certificate authority.
+The most automated way is to use a provider supporting the [ACME protocol](https://datatracker.ietf.org/doc/html/rfc8555) 
+such as [Let's Encrypt](https://letsencrypt.org/), [ZeroSSL](https://zerossl.com/) or [Buypass Go SSL](https://www.buypass.com/ssl/products/acme).
+
+If you are only testing Garage, you can generate a self-signed certificate to follow the documentation:
+
+```bash
+openssl req \
+    -new \
+    -x509 \
+    -keyout /tmp/garage.key \
+    -out /tmp/garage.crt \
+    -nodes  \
+    -subj "/C=XX/ST=XX/L=XX/O=XX/OU=XX/CN=localhost/emailAddress=X@X.XX" \
+    -addext "subjectAltName = DNS:localhost, IP:127.0.0.1"
+
+cat /tmp/garage.key /tmp/garage.crt > /tmp/garage.pem
+```
+
+Be careful as you will need to allow self signed certificates in your client.
+For example, with minio, you must add the `--insecure` flag.
+An example:
+
+```bash
+mc ls --insecure garage/
+```
+
+## socat (only for testing purposes)
+
+If you want to test Garage with a TLS frontend, socat can do it for you in a single command:
+
+```bash
+socat \
+"openssl-listen:443,\
+reuseaddr,\
+fork,\
+verify=0,\
+cert=/tmp/garage.pem" \
+tcp4-connect:localhost:3900
+```
+
+## Nginx
+
+Nginx is a well-known reverse proxy suitable for production.
+We do the configuration in 3 steps: first we define the upstream blocks ("the backends")
+then we define the server blocks ("the frontends") for the S3 endpoint and finally for the web endpoint.
+
+The following configuration blocks can be all put in the same `/etc/nginx/sites-available/garage.conf`.
+To make your configuration active, run `ln -s /etc/nginx/sites-available/garage.conf /etc/nginx/sites-enabled/`.
+If you directly put the instructions in the root `nginx.conf`, keep in mind that these configurations must be enclosed inside a `http { }` block.
+
+And do not forget to reload nginx with `systemctl reload nginx` or `nginx -s reload`.
+
+### Exposing the S3 endpoints
+
+First, we need to tell to nginx how to access our Garage cluster.
+Because we have multiple nodes, we want to leverage all of them by spreading the load.
+In nginx, we can do that with the `upstream` directive.
+
+Then in a `server` directive, we define the vhosts, the TLS certificates and the proxy rule.
+
+A possible configuration:
+
+```nginx
+upstream s3_backend {
+  # If you have a garage instance locally.
+  server 127.0.0.1:3900;
+  # You can also put your other instances.
+  server 192.168.1.3:3900;
+  # Domain names also work.
+  server garage1.example.com:3900;
+  # A "backup" server is only used if all others have failed.
+  server garage-remote.example.com:3900 backup;
+  # You can assign weights if you have some servers
+  # that can serve more requests than others.
+  server garage2.example.com:3900 weight=2;
+}
+
+server {
+  listen [::]:443 http2 ssl;
+
+  ssl_certificate     /tmp/garage.crt;
+  ssl_certificate_key /tmp/garage.key;
+
+  # You need multiple server names here:
+  #  - s3.garage.tld is used for path-based s3 requests
+  #  - *.s3.garage.tld is used for vhost-based s3 requests
+  server_name s3.garage.tld *.s3.garage.tld;
+
+  location / {
+    proxy_pass http://s3_backend;
+    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+    proxy_set_header Host $host;
+    # Disable buffering to a temporary file.
+    proxy_max_temp_file_size 0;
+  }
+}
+```
+
+### Exposing the web endpoint
+
+To better understand the logic involved, you can refer to the [Exposing buckets as websites](/cookbook/exposing_websites.html) section.
+Otherwise, the configuration is very similar to the S3 endpoint.
+You must only adapt `upstream` with the web port instead of the s3 port and change the `server_name` and `proxy_pass` entry
+
+A possible configuration:
+
+
+```nginx
+upstream web_backend {
+  server 127.0.0.1:3902;
+  server 192.168.1.3:3902;
+  server garage1.example.com:3902;
+  server garage2.example.com:3902 weight=2;
+}
+
+server {
+  listen [::]:443 http2 ssl;
+
+  ssl_certificate     /tmp/garage.crt;
+  ssl_certificate_key /tmp/garage.key;
+
+  # You need multiple server names here:
+  #  - *.web.garage.tld is used for your users wanting a website without reserving a domain name
+  #  - example.com, my-site.tld, etc. are reserved domain name by your users that chose to host their website as a garage's bucket
+  server_name *.web.garage.tld example.com my-site.tld;
+
+  location / {
+    proxy_pass http://web_backend;
+    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+    proxy_set_header Host $host;
+  }
+}
+```
+
+## Apache httpd
+
+@TODO
+
+## Traefik v2
+
+We will see in this part how to set up a reverse proxy with [Traefik](https://docs.traefik.io/).
+
+Here is [a basic configuration file](https://doc.traefik.io/traefik/https/acme/#configuration-examples):
+
+```toml
+[entryPoints]
+  [entryPoints.web]
+    address = ":80"
+
+  [entryPoints.websecure]
+    address = ":443"
+
+[certificatesResolvers.myresolver.acme]
+  email = "your-email@example.com"
+  storage = "acme.json"
+  [certificatesResolvers.myresolver.acme.httpChallenge]
+    # used during the challenge
+    entryPoint = "web"
+```
+
+### Add Garage service
+
+To add Garage on Traefik you should declare a new service using its IP address (or hostname) and port:
+
+```toml
+[http.services]
+  [http.services.my_garage_service.loadBalancer]
+    [[http.services.my_garage_service.loadBalancer.servers]]
+      url = "http://xxx.xxx.xxx.xxx"
+      port = 3900
+```
+
+It's possible to declare multiple Garage servers as back-ends:
+
+```toml
+[http.services]
+    [[http.services.my_garage_service.loadBalancer.servers]]
+      url = "http://xxx.xxx.xxx.xxx"
+      port = 3900
+    [[http.services.my_garage_service.loadBalancer.servers]]
+      url = "http://yyy.yyy.yyy.yyy"
+      port = 3900
+    [[http.services.my_garage_service.loadBalancer.servers]]
+      url = "http://zzz.zzz.zzz.zzz"
+      port = 3900
+```
+
+Traefik can remove unhealthy servers automatically with [a health check configuration](https://doc.traefik.io/traefik/routing/services/#health-check):
+
+```
+[http.services]
+  [http.services.my_garage_service.loadBalancer]
+    [http.services.my_garage_service.loadBalancer.healthCheck]
+      path = "/"
+      interval = "60s"
+      timeout = "5s"
+```
+
+### Adding a website
+
+To add a new website, add the following declaration to your Traefik configuration file:
+
+```toml
+[http.routers]
+  [http.routers.my_website]
+    rule = "Host(`yoururl.example.org`)"
+    service = "my_garage_service"
+    entryPoints = ["web"]
+```
+
+Enable HTTPS access to your website with the following configuration section ([documentation](https://doc.traefik.io/traefik/https/overview/)):
+
+```toml
+...
+    entryPoints = ["websecure"]
+    [http.routers.my_website.tls]
+      certResolver = "myresolver"
+...
+```
+
+### Adding gzip compression
+
+Add the following configuration section [to compress response](https://doc.traefik.io/traefik/middlewares/http/compress/) using [gzip](https://developer.mozilla.org/en-US/docs/Glossary/GZip_compression) before sending them to the client:
+
+```toml
+[http.routers]
+  [http.routers.my_website]
+    ...
+    middlewares = ["gzip_compress"]
+    ...
+[http.middlewares]
+  [http.middlewares.gzip_compress.compress]
+```
+
+### Add caching response
+
+Traefik's caching middleware is only available on [entreprise version](https://doc.traefik.io/traefik-enterprise/middlewares/http-cache/), however the freely-available [Souin plugin](https://github.com/darkweak/souin#tr%C3%A6fik-container) can also do the job. (section to be completed)
+
+### Complete example

+
+## Caddy
+
+Your Caddy configuration can be as simple as:
+
+```caddy
+s3.garage.tld, *.s3.garage.tld {
+	reverse_proxy localhost:3900 192.168.1.2:3900 example.tld:3900
+}
+
+*.web.garage.tld {
+	reverse_proxy localhost:3902 192.168.1.2:3900 example.tld:3900
+}
+
+admin.garage.tld {
+	reverse_proxy localhost:3903
+}
+```
+
+But at the same time, the `reverse_proxy` is very flexible.
+For a production deployment, you should [read its documentation](https://caddyserver.com/docs/caddyfile/directives/reverse_proxy) as it supports features like DNS discovery of upstreams, load balancing with checks, streaming parameters, etc.

+  - protocols and data structures remained the same ➡️ this is a **straightforward upgrade**
+  - protocols or data structures changed  ➡️  this is an **advanced upgrade**
+
+You can quickly now what type of update you will have to operate by looking at the version identifier.
+Following the [SemVer ](https://semver.org/) terminology, if only the *patch* number changed, it will only need a straightforward upgrade.
+Example: an upgrade from v0.6.0 from v0.6.1 is a straightforward upgrade.
+If the *minor* or *major* number changed however, you will have to do an advanced upgrade. Example: from v0.6.1 to v0.7.0.
+
+Migrations are designed to be run only between contiguous versions (from a *major*.*minor* perspective, *patches* can be skipped).
+Example: migrations from v0.6.1 to v0.7.0 and from v0.6.0 to v0.7.0 are supported but migrations from v0.5.0 to v0.7.0 are not supported.
+
+## Straightforward upgrades
+
+Straightforward upgrades do not imply cluster downtime.
+Before upgrading, you should still read [the changelog](https://git.deuxfleurs.fr/Deuxfleurs/garage/releases) and ideally test your deployment on a staging cluster before.
+
+When you are ready, start by checking the health of your cluster.
+You can force some checks with `garage repair`, we recommend at least running `garage repair --all-nodes --yes` that is very quick to run (less than a minute).
+You will see that the command correctly terminated in the logs of your daemon.
+
+Finally, you can simply upgrades nodes one by one. 
+For each node: stop it, install the new binary, edit the configuration if needed, restart it. 
+
+## Advanced upgrades
+
+Advanced upgrades will imply cluster downtime.
+Before upgrading, you must read [the changelog](https://git.deuxfleurs.fr/Deuxfleurs/garage/releases) and you must test your deployment on a staging cluster before.
+
+From a high level perspective, an advanced upgrade looks like this:
+  1. Make sure the health of your cluster is good (see `garage repair`)
+  2. Disable API access (comment the configuration in your reverse proxy)
+  3. Check that your cluster is idle
+  4. Stop the whole cluster
+  5. Backup the metadata folder of all your nodes, so that you will be able to restore it quickly if the upgrade fails (blocks being immutable, they should not be impacted)
+  6. Install the new binary, update the configuration
+  7. Start the whole cluster
+  8. If needed, run the corresponding migration from `garage migrate`
+  9. Make sure the health of your cluster is good
+  10. Enable API access (uncomment the configuration in your reverse proxy)
+  11. Monitor your cluster while load comes back, check that all your applications are happy with this new version
+
+We write guides for each advanced upgrade, they are stored under the "Working Documents" section of this documentation.

+## Request routing logic
+
+Data retrieval requests to Garage endpoints (S3 API and websites) are resolved 
+to an individual object in a bucket. Since objects are replicated to multiple nodes 
+Garage must ensure consistency before answering the request.
+
+### Using quorum to ensure consistency
+
+Garage ensures consistency by attempting to establish a quorum with the
+data nodes responsible for the object. When a majority of the data nodes
+have provided metadata on a object Garage can then answer the request.
+
+When a request arrives Garage will, assuming the recommended 3 replicas, perform the following actions:
+
+- Make a request to the two preferred nodes for object metadata
+- Try the third node if one of the two initial requests fail
+- Check that the metadata from at least 2 nodes match
+- Check that the object hasn't been marked deleted
+- Answer the request with inline data from metadata if object is small enough
+- Or get data blocks from the preferred nodes and answer using the assembled object
+
+Garage dynamically determines which nodes to query based on health, preference, and 
+which nodes actually host a given data. Garage has no concept of "primary" so any 
+healthy node with the data can be used as long as a quorum is reached for the metadata.
+
+### Node health
+
+Garage keeps a TCP session open to each node in the cluster and periodically pings them. If a connection
+cannot be established, or a node fails to answer a number of pings, the target node is marked as failed.
+Failed nodes are not used for quorum or other internal requests.
+
+### Node preference
+
+Garage prioritizes which nodes to query according to a few criteria:
+
+- A node always prefers itself if it can answer the request
+- Then the node prioritizes nodes in the same zone
+- Finally the nodes with the lowest latency are prioritized 
+
+

 ## Uploading and downlading from Garage
 
-We recommend the use of MinIO Client to interact with Garage files (`mc`).
-Instructions to install it and use it are provided on the
-[MinIO website](https://docs.min.io/docs/minio-client-quickstart-guide.html).
-Before reading the following, you need a working `mc` command on your path.
+To download and upload files on garage, we can use a third-party tool named `awscli`.
 
-Note that on certain Linux distributions such as Arch Linux, the Minio client binary
-is called `mcli` instead of `mc` (to avoid name clashes with the Midnight Commander).
 
-#### Configure `mc`
+### Install and configure `awscli`
 
-You need your access key and secret key created above.
-We will assume you are invoking `mc` on the same machine as the Garage server,
-your S3 API endpoint is therefore `http://127.0.0.1:3900`.
-For this whole configuration, you must set an alias name: we chose `my-garage`, that you will used for all commands.
-
-Adapt the following command accordingly and run it:
+If you have python on your system, you can install it with:
 
 ```bash
-mc alias set \
-  my-garage \
-  http://127.0.0.1:3900 \
-  <access key> \
-  <secret key> \
-  --api S3v4
+python -m pip install --user awscli
 ```
 
-You must also add an environment variable to your configuration to
-inform MinIO of our region (`garage` by default, corresponding to the `s3_region` parameter
-in the configuration file).
-The best way is to add the following snippet to your `$HOME/.bash_profile`
-or `$HOME/.bashrc` file:
+Now that `awscli` is installed, you must configure it to talk to your Garage instance,
+with your key. There are multiple ways to do that, the simplest one is to create a file
+named `~/.awsrc` with this content:
 
 ```bash
-export MC_REGION=garage
+export AWS_ACCESS_KEY_ID=xxxx      # put your Key ID here
+export AWS_SECRET_ACCESS_KEY=xxxx  # put your Secret key here
+export AWS_DEFAULT_REGION='garage'
+export AWS_ENDPOINT='http://localhost:3900'
+
+function aws { command aws --endpoint-url $AWS_ENDPOINT $@ ; }
+aws --version
 ```
 
-#### Use `mc`
-
-You can not list buckets from `mc` currently.
-
-But the following commands and many more should work:
+Now, each time you want to use `awscli` on this target, run:
 
 ```bash
-mc cp image.png my-garage/nextcloud-bucket
-mc cp my-garage/nextcloud-bucket/image.png .
-mc ls my-garage/nextcloud-bucket
-mc mirror localdir/ my-garage/another-bucket
+source ~/.awsrc
 ```
 
+*You can create multiple files with different names if you 
+have multiple Garage clusters or different keys.
+Switching from one cluster to another is as simple as
+sourcing the right file.*
 
-#### Other tools for interacting with Garage
+### Example usage of `awscli`
+
+```bash
+# list buckets
+aws s3 ls
+
+# list objects of a bucket
+aws s3 ls s3://my_files
+
+# copy from your filesystem to garage
+aws s3 cp /proc/cpuinfo s3://my_files/cpuinfo.txt
+
+# copy from garage to your filesystem
+aws s3 cp s3/my_files/cpuinfo.txt /tmp/cpuinfo.txt
+```
+
+Note that you can use `awscli` for more advanced operations like
+creating a bucket, pre-signing a request or managing your website.

+- `admin_token`: the token for accessing all of the other administration
+  endpoints (if this token is not set in the config file, access to these
+  endpoints is disabled entirely).
+
+These tokens are used as simple HTTP bearer tokens. In other words, to
+authenticate access to an admin API endpoint, add the following HTTP header
+to your request:
+
+```
+Authorization: Bearer <token>
+```
+
+## Administration API endpoints
+
+### Metrics-related endpoints
+
+#### Metrics `GET /metrics`
+
+Returns internal Garage metrics in Prometheus format.
+
+### Cluster operations
+
+These endpoints are defined on a dedicated [Redocly page](https://garagehq.deuxfleurs.fr/api/garage-admin-v0.html). You can also download its [OpenAPI specification](https://garagehq.deuxfleurs.fr/api/garage-admin-v0.yml).
+
+Requesting the API from the command line can be as simple as running:
+
+```bash
+curl -H 'Authorization: Bearer s3cr3t' http://localhost:3903/v0/status | jq
+```
+
+For more advanced use cases, we recommend using a SDK.

+
+The following gives details about each available configuration option.
+
+## Available configuration options
+
+### `metadata_dir`
+
+The directory in which Garage will store its metadata. This contains the node identifier,
+the network configuration and the peer list, the list of buckets and keys as well
+as the index of all objects, object version and object blocks.
+
+Store this folder on a fast SSD drive if possible to maximize Garage's performance.
+
+### `data_dir`
+
+The directory in which Garage will store the data blocks of objects.
+This folder can be placed on an HDD. The space available for `data_dir`
+should be counted to determine a node's capacity
+when [adding it to the cluster layout](@/documentation/cookbook/real-world.md).
+
+### `db_engine` (since `v0.8.0`)
+
+By default, Garage uses the Sled embedded database library
+to store its metadata on-disk. Since `v0.8.0`, Garage can use alternative storage backends as follows:
+
+| DB engine | `db_engine` value | Database path |
+| --------- | ----------------- | ------------- |
+| [Sled](https://sled.rs) | `"sled"` | `<metadata_dir>/db/` |
+| [LMDB](https://www.lmdb.tech) | `"lmdb"` | `<metadata_dir>/db.lmdb/` |
+| [Sqlite](https://sqlite.org) | `"sqlite"` | `<metadata_dir>/db.sqlite` |
+
+Performance characteristics of the different DB engines are as follows:
+
+- Sled: the default database engine, which tends to produce
+  large data files and also has performance issues, especially when the metadata folder
+  is on a traditionnal HDD and not on SSD.
+- LMDB: the recommended alternative on 64-bit systems,
+  much more space-efficiant and slightly faster. Note that the data format of LMDB is not portable
+  between architectures, so for instance the Garage database of an x86-64
+  node cannot be moved to an ARM64 node. Also note that, while LMDB can technically be used on 32-bit systems,
+  this will limit your node to very small database sizes due to how LMDB works; it is therefore not recommended.
+- Sqlite: Garage supports Sqlite as a storage backend for metadata,
+  however it may have issues and is also very slow in its current implementation,
+  so it is not recommended to be used for now.
+
+It is possible to convert Garage's metadata directory from one format to another with a small utility named `convert_db`,
+which can be downloaded at the following locations:
+[for amd64](https://garagehq.deuxfleurs.fr/_releases/convert_db/amd64/convert_db),
+[for i386](https://garagehq.deuxfleurs.fr/_releases/convert_db/i386/convert_db),
+[for arm64](https://garagehq.deuxfleurs.fr/_releases/convert_db/arm64/convert_db),
+[for arm](https://garagehq.deuxfleurs.fr/_releases/convert_db/arm/convert_db).
+The `convert_db` utility is used as folows:
+
+```
+convert-db -a <input db engine> -i <input db path> \
+  		   -b <output db engine> -o <output db path>
+```
+
+Make sure to specify the full database path as presented in the table above,
+and not just the path to the metadata directory.
+
+### `block_size`
+
+Garage splits stored objects in consecutive chunks of size `block_size`
+(except the last one which might be smaller). The default size is 1MB and
+should work in most cases. We recommend increasing it to e.g. 10MB if
+you are using Garage to store large files and have fast network connections
+between all nodes (e.g. 1gbps).
+
+If you are interested in tuning this, feel free to do so (and remember to
+report your findings to us!). When this value is changed for a running Garage
+installation, only files newly uploaded will be affected. Previously uploaded
+files will remain available. This however means that chunks from existing files
+will not be deduplicated with chunks from newly uploaded files, meaning you
+might use more storage space that is optimally possible.
+
+### `sled_cache_capacity`
+
+This parameter can be used to tune the capacity of the cache used by
+[sled](https://sled.rs), the database Garage uses internally to store metadata.
+Tune this to fit the RAM you wish to make available to your Garage instance.
+This value has a conservative default (128MB) so that Garage doesn't use too much
+RAM by default, but feel free to increase this for higher performance.
+
+### `sled_flush_every_ms`
+
+This parameters can be used to tune the flushing interval of sled.
+Increase this if sled is thrashing your SSD, at the risk of losing more data in case
+of a power outage (though this should not matter much as data is replicated on other
+nodes). The default value, 2000ms, should be appropriate for most use cases.
+
+### `replication_mode`
+
+Garage supports the following replication modes:
+
+- `none` or `1`: data stored on Garage is stored on a single node. There is no
+  redundancy, and data will be unavailable as soon as one node fails or its
+  network is disconnected.  Do not use this for anything else than test
+  deployments.
+
+- `2`: data stored on Garage will be stored on two different nodes, if possible
+  in different zones. Garage tolerates one node failure, or several nodes
+  failing but all in a single zone (in a deployment with at least two zones),
+  before losing data. Data remains available in read-only mode when one node is
+  down, but write operations will fail.
+
+  - `2-dangerous`: a variant of mode `2`, where written objects are written to
+    the second replica asynchronously. This means that Garage will return `200
+    OK` to a PutObject request before the second copy is fully written (or even
+    before it even starts being written).  This means that data can more easily
+    be lost if the node crashes before a second copy can be completed.  This
+    also means that written objects might not be visible immediately in read
+    operations.  In other words, this mode severely breaks the consistency and
+    durability guarantees of standard Garage cluster operation.  Benefits of
+    this mode: you can still write to your cluster when one node is
+    unavailable.
+
+- `3`: data stored on Garage will be stored on three different nodes, if
+  possible each in a different zones.  Garage tolerates two node failure, or
+  several node failures but in no more than two zones (in a deployment with at
+  least three zones), before losing data. As long as only a single node fails,
+  or node failures are only in a single zone, reading and writing data to
+  Garage can continue normally.
+
+  - `3-degraded`: a variant of replication mode `3`, that lowers the read
+    quorum to `1`, to allow you to read data from your cluster when several
+    nodes (or nodes in several zones) are unavailable.  In this mode, Garage
+    does not provide read-after-write consistency anymore.  The write quorum is
+    still 2, ensuring that data successfully written to Garage is stored on at
+    least two nodes.
+
+  - `3-dangerous`: a variant of replication mode `3` that lowers both the read
+    and write quorums to `1`, to allow you to both read and write to your
+    cluster when several nodes (or nodes in several zones) are unavailable.  It
+    is the least consistent mode of operation proposed by Garage, and also one
+    that should probably never be used.
+
+Note that in modes `2` and `3`,
+if at least the same number of zones are available, an arbitrary number of failures in 
+any given zone is tolerated as copies of data will be spread over several zones.
+
+**Make sure `replication_mode` is the same in the configuration files of all nodes.
+Never run a Garage cluster where that is not the case.**
+
+The quorums associated with each replication mode are described below:
+
+| `replication_mode` | Number of replicas | Write quorum | Read quorum | Read-after-write consistency? |
+| ------------------ | ------------------ | ------------ | ----------- | ----------------------------- |
+| `none` or `1`      | 1                  | 1            | 1           | yes                           |
+| `2`                | 2                  | 2            | 1           | yes                           |
+| `2-dangerous`      | 2                  | 1            | 1           | NO                            |
+| `3`                | 3                  | 2            | 2           | yes                           |
+| `3-degraded`       | 3                  | 2            | 1           | NO                            |
+| `3-dangerous`      | 3                  | 1            | 1           | NO                            |
+
+Changing the `replication_mode` between modes with the same number of replicas
+(e.g. from `3` to `3-degraded`, or from `2-dangerous` to `2`), can be done easily by
+just changing the `replication_mode` parameter in your config files and restarting all your
+Garage nodes.
+
+It is also technically possible to change the replication mode to a mode with a
+different numbers of replicas, although it's a dangerous operation that is not
+officially supported.  This requires you to delete the existing cluster layout
+and create a new layout from scratch, meaning that a full rebalancing of your
+cluster's data will be needed.  To do it, shut down your cluster entirely,
+delete the `custer_layout` files in the meta directories of all your nodes,
+update all your configuration files with the new `replication_mode` parameter,
+restart your cluster, and then create a new layout with all the nodes you want
+to keep.  Rebalancing data will take some time, and data might temporarily
+appear unavailable to your users.  It is recommended to shut down public access
+to the cluster while rebalancing is in progress.  In theory, no data should be
+lost as rebalancing is a routine operation for Garage, although we cannot
+guarantee you that everything will go right in such an extreme scenario.
+
+### `compression_level`
+
+Zstd compression level to use for storing blocks.
+
+Values between `1` (faster compression) and `19` (smaller file) are standard compression
+levels for zstd. From `20` to `22`, compression levels are referred as "ultra" and must be
+used with extra care as it will use lot of memory. A value of `0` will let zstd choose a
+default value (currently `3`). Finally, zstd has also compression designed to be faster
+than default compression levels, they range from `-1` (smaller file) to `-99` (faster 
+compression).
+
+If you do not specify a `compression_level` entry, Garage will set it to `1` for you. With
+this parameters, zstd consumes low amount of cpu and should work faster than line speed in
+most situations, while saving some space and intra-cluster
+bandwidth.
+
+If you want to totally deactivate zstd in Garage, you can pass the special value `'none'`. No
+zstd related code will be called, your chunks will be stored on disk without any processing.
+
+Compression is done synchronously, setting a value too high will add latency to write queries.
+
+This value can be different between nodes, compression is done by the node which receive the
+API call.
+
+### `rpc_secret`
+
+Garage uses a secret key that is shared between all nodes of the cluster
+in order to identify these nodes and allow them to communicate together.
+This key should be specified here in the form of a 32-byte hex-encoded
+random string. Such a string can be generated with a command
+such as `openssl rand -hex 32`.
+
+### `rpc_bind_addr`
+
+The address and port on which to bind for inter-cluster communcations
+(reffered to as RPC for remote procedure calls).
+The port specified here should be the same one that other nodes will used to contact
+the node, even in the case of a NAT: the NAT should be configured to forward the external
+port number to the same internal port nubmer. This means that if you have several nodes running
+behind a NAT, they should each use a different RPC port number.
+
+### `rpc_public_addr`
+
+The address and port that other nodes need to use to contact this node for
+RPC calls.  **This parameter is optional but recommended.** In case you have
+a NAT that binds the RPC port to a port that is different on your public IP,
+this field might help making it work.
+
+### `bootstrap_peers`
+
+A list of peer identifiers on which to contact other Garage peers of this cluster.
+These peer identifiers have the following syntax:
+
+```
+<node public key>@<node public IP or hostname>:<port>
+```
+
+In the case where `rpc_public_addr` is correctly specified in the
+configuration file, the full identifier of a node including IP and port can
+be obtained by running `garage node id` and then included directly in the
+`bootstrap_peers` list of other nodes.  Otherwise, only the node's public
+key will be returned by `garage node id` and you will have to add the IP
+yourself.
+
+
+## The `[consul_discovery]` section
+
+Garage supports discovering other nodes of the cluster using Consul.  For this
+to work correctly, nodes need to know their IP address by which they can be
+reached by other nodes of the cluster, which should be set in `rpc_public_addr`.
+
+### `consul_http_addr` and `service_name`
+
+The `consul_http_addr` parameter should be set to the full HTTP(S) address of the Consul server.
+
+### `service_name`
+
+`service_name` should be set to the service name under which Garage's
+RPC ports are announced.
+
+### `client_cert`, `client_key`
+
+TLS client certificate and client key to use when communicating with Consul over TLS. Both are mandatory when doing so.
+
+### `ca_cert`
+
+TLS CA certificate to use when communicating with Consul over TLS.
+
+### `tls_skip_verify`
+
+Skip server hostname verification in TLS handshake.
+`ca_cert` is ignored when this is set.
+
+
+## The `[kubernetes_discovery]` section
+
+Garage supports discovering other nodes of the cluster using kubernetes custom
+resources. For this to work, a `[kubernetes_discovery]` section must be present
+with at least the `namespace` and `service_name` parameters.
+
+### `namespace`
+
+`namespace` sets the namespace in which the custom resources are
+configured.
+
+### `service_name`
+
+`service_name` is added as a label to the advertised resources to
+filter them, to allow for multiple deployments in a single namespace.
+
+### `skip_crd`
+
+`skip_crd` can be set to true to disable the automatic creation and
+patching of the `garagenodes.deuxfleurs.fr` CRD. You will need to create the CRD
+manually.
+
+
+## The `[s3_api]` section
+
+### `api_bind_addr`
+
+The IP and port on which to bind for accepting S3 API calls.
+This endpoint does not suport TLS: a reverse proxy should be used to provide it.
+
+### `s3_region`
+
+Garage will accept S3 API calls that are targetted to the S3 region defined here.
+API calls targetted to other regions will fail with a AuthorizationHeaderMalformed error
+message that redirects the client to the correct region.
+
+### `root_domain` {#root_domain}
+
+The optionnal suffix to access bucket using vhost-style in addition to path-style request.
+Note path-style requests are always enabled, whether or not vhost-style is configured.
+Configuring vhost-style S3 required a wildcard DNS entry, and possibly a wildcard TLS certificate,
+but might be required by softwares not supporting path-style requests.
+
+If `root_domain` is `s3.garage.eu`, a bucket called `my-bucket` can be interacted with
+using the hostname `my-bucket.s3.garage.eu`.
+
+
+
+## The `[s3_web]` section
+
+Garage allows to publish content of buckets as websites. This section configures the
+behaviour of this module.
+
+### `bind_addr`
+
+The IP and port on which to bind for accepting HTTP requests to buckets configured
+for website access.
+This endpoint does not suport TLS: a reverse proxy should be used to provide it.
+
+### `root_domain`
+
+The optionnal suffix appended to bucket names for the corresponding HTTP Host.
+
+For instance, if `root_domain` is `web.garage.eu`, a bucket called `deuxfleurs.fr`
+will be accessible either with hostname `deuxfleurs.fr.web.garage.eu`
+or with hostname `deuxfleurs.fr`.
+
+
+## The `[admin]` section
+
+Garage has a few administration capabilities, in particular to allow remote monitoring. These features are detailed below.
+
+### `api_bind_addr`
+
+If specified, Garage will bind an HTTP server to this port and address, on
+which it will listen to requests for administration features.
+See [administration API reference](@/documentation/reference-manual/admin-api.md) to learn more about these features.
+
+### `metrics_token` (since version 0.7.2)
+
+The token for accessing the Metrics endpoint. If this token is not set in
+the config file, the Metrics endpoint can be accessed without access
+control.
+
+You can use any random string for this value. We recommend generating a random token with `openssl rand -hex 32`.
+
+### `admin_token` (since version 0.7.2)
+
+The token for accessing all of the other administration endpoints.  If this
+token is not set in the config file, access to these endpoints is disabled
+entirely.
+
+You can use any random string for this value. We recommend generating a random token with `openssl rand -hex 32`.
+
+### `trace_sink`
+
+Optionnally, the address of an Opentelemetry collector.  If specified,
+Garage will send traces in the Opentelemetry format to this endpoint. These
+trace allow to inspect Garage's operation when it handles S3 API requests.

+
+
+### S3 API
+
+The main goal of Garage is to provide an object storage service that is compatible with the
+[S3 API](https://docs.aws.amazon.com/AmazonS3/latest/API/Welcome.html) from Amazon Web Services.
+We try to adhere as strictly as possible to the semantics of the API as implemented by Amazon
+and other vendors such as Minio or CEPH.
+
+Of course Garage does not implement the full span of API endpoints that AWS S3 does;
+the exact list of S3 features implemented by Garage can be found [on our S3 compatibility page](@/documentation/reference-manual/s3-compatibility.md).
+
+### Geo-distribution
+
+Garage allows you to store copies of your data in multiple geographical locations in order to maximize resilience
+to adverse events, such as network/power outages or hardware failures.
+This allows Garage to run very well even at home, using consumer-grade Internet connectivity
+(such as FTTH) and power, as long as cluster nodes can be spawned at several physical locations.
+Garage exploits knowledge of the capacity and physical location of each storage node to design
+a storage plan that best exploits the available storage capacity while satisfying the geo-distributed replication constraint.
+
+To learn more about geo-distributed Garage clusters,
+read our documentation on [setting up a real-world deployment](@/documentation/cookbook/real-world.md).
+
+### Standalone/self-contained
+
+Garage is extremely simple to deploy, and does not depend on any external service to run.
+This makes setting up and administering storage clusters, we hope, as easy as it could be.
+
+### Flexible topology
+
+A Garage cluster can very easily evolve over time, as storage nodes are added or removed.
+Garage will automatically rebalance data between nodes as needed to ensure the desired number of copies.
+Read about cluster layout management [here](@/documentation/reference-manual/layout.md).
+
+### No RAFT slowing you down
+
+It might seem strange to tout the absence of something as a desirable feature,
+but this is in fact a very important point! Garage does not use RAFT or another
+consensus algorithm internally to order incoming requests: this means that all requests
+directed to a Garage cluster can be handled independently of one another instead
+of going through a central bottleneck (the leader node).
+As a consequence, requests can be handled much faster, even in cases where latency
+between cluster nodes is important (see our [benchmarks](@/documentation/design/benchmarks/index.md) for data on this).
+This is particularly usefull when nodes are far from one another and talk to one other through standard Internet connections.
+
+### Several replication modes
+
+Garage supports a variety of replication modes, with 1 copy, 2 copies or 3 copies of your data,
+and with various levels of consistency, in order to adapt to a variety of usage scenarios.
+Read our reference page on [supported replication modes](@/documentation/reference-manual/configuration.md#replication-mode)
+to select the replication mode best suited to your use case (hint: in most cases, `replication_mode = "3"` is what you want).
+
+### Web server for static websites
+
+A storage bucket can easily be configured to be served directly by Garage as a static web site.
+Domain names for multiple websites directly map to bucket names, making it easy to build
+a platform for your users to autonomously build and host their websites over Garage.
+Surprisingly, none of the other alternative S3 implementations we surveyed (such as Minio
+or CEPH) support publishing static websites from S3 buckets, a feature that is however
+directly inherited from S3 on AWS.
+Read more on our [dedicated documentation page](@/documentation/cookbook/exposing-websites.md).
+
+### Bucket names as aliases
+
+In Garage, a bucket may have several names, known as aliases.
+Aliases can easily be added and removed on demand:
+this allows to easily rename buckets if needed
+without having to copy all of their content, something that cannot be done on AWS.
+For buckets served as static websites, having multiple aliases for a bucket can allow
+exposing the same content under different domain names.
+
+Garage also supports bucket aliases which are local to a single user:
+this allows different users to have different buckets with the same name, thus avoiding naming collisions.
+This can be helpfull for instance if you want to write an application that creates per-user buckets with always the same name.
+
+This feature is totally invisible to S3 clients and does not break compatibility with AWS.
+
+### Cluster administration API
+
+Garage provides a fully-fledged REST API to administer your cluster programatically.
+Functionality included in the admin API include: setting up and monitoring
+cluster nodes, managing access credentials, and managing storage buckets and bucket aliases.
+A full reference of the administration API is available [here](@/documentation/reference-manual/admin-api.md).
+
+### Metrics and traces
+
+Garage makes some internal metrics available in the Prometheus data format,
+which allows you to build interactive dashboards to visualize the load and internal state of your storage cluster.
+
+For developpers and performance-savvy administrators,
+Garage also supports exporting traces of what it does internally in OpenTelemetry format.
+This allows to monitor the time spent at various steps of the processing of requests,
+in order to detect potential performance bottlenecks.
+
+### Kubernetes and Nomad integrations
+
+Garage can automatically discover other nodes in the cluster thanks to integration
+with orchestrators such as Kubernetes and Nomad (when used with Consul).
+This eases the configuration of your cluster as it removes one step where nodes need
+to be manually connected to one another.
+
+### Support for changing IP addresses
+
+As long as all of your nodes don't change their IP address at the same time,
+Garage should be able to tolerate nodes with changing/dynamic IP addresses,
+as nodes will regularly exchange the IP addresses of their peers and try to
+reconnect using newer addresses when existing connections are broken.
+
+### K2V API (experimental)
+
+As part of an ongoing research project, Garage can expose an experimental key/value storage API called K2V.
+K2V is made for the storage and retrieval of many small key/value pairs that need to be processed in bulk.
+This completes the S3 API with an alternative that can be used to easily store and access metadata
+related to objects stored in an S3 bucket.
+
+In the context of our research project, [Aérogramme](https://aerogramme.deuxfleurs.fr),
+K2V is used to provide metadata and log storage for operations on encrypted e-mail storage.
+
+Learn more on the specification of K2V [here](https://git.deuxfleurs.fr/Deuxfleurs/garage/src/branch/k2v/doc/drafts/k2v-spec.md)
+and on how to enable it in Garage [here](@/documentation/reference-manual/k2v.md).

+
+Starting with version 0.7.2, Garage introduces an optionnal feature, K2V,
+which is an alternative storage API designed to help efficiently store
+many small values in buckets (in opposition to S3 which is more designed
+to store large blobs).
+
+K2V is currently disabled at compile time in all builds, as the
+specification is still subject to changes. To build a Garage version with
+K2V, the Cargo feature flag `k2v` must be activated.  Special builds with
+the `k2v` feature flag enabled can be obtained from our download page under
+"Extra builds": such builds can be identified easily as their tag name ends
+with `-k2v` (example: `v0.7.2-k2v`).
+
+The specification of the K2V API can be found
+[here](https://git.deuxfleurs.fr/Deuxfleurs/garage/src/branch/k2v/doc/drafts/k2v-spec.md).
+This document also includes a high-level overview of K2V's design.
+
+The K2V API uses AWSv4 signatures for authentification, same as the S3 API.
+The AWS region used for signature calculation is always the same as the one
+defined for the S3 API in the config file.
+
+## Enabling and using K2V
+
+To enable K2V, download and run a build that has the `k2v` feature flag
+enabled, or produce one yourself. Then, add the following section to your
+configuration file:
+
+```toml
+[k2v_api]
+api_bind_addr = "<ip>:<port>"
+```
+
+Please select a port number that is not already in use by another API
+endpoint (S3 api, admin API) or by the RPC server.
+
+We provide an early-stage K2V client library for Rust which can be imported by adding the following to your `Cargo.toml` file:
+
+```toml
+k2v-client = { git = "https://git.deuxfleurs.fr/Deuxfleurs/garage.git" }
+```
+
+There is also a simple CLI utility which can be built from source in the
+following way:
+
+```sh
+git clone https://git.deuxfleurs.fr/Deuxfleurs/garage.git
+cd garage/src/k2v-client
+cargo build --features cli --bin k2v-cli
+```
+
+The CLI utility is self-documented, run `k2v-cli --help` to learn how to use
+it. There is also a short README.md in the `src/k2v-client` folder with some
+instructions.

 The cluster layout in Garage is a table that assigns to each node a role in
 the cluster. The role of a node in Garage can either be a storage node with
 a certain capacity, or a gateway node that does not store data and is only
 used as an API entry point for faster cluster access.
-An introduction to building cluster layouts can be found in the [production deployment](/cookbook/real_world.md) page.

-# Backups (restic, duplicity...)
-
-Backups are essential for disaster recovery but they are not trivial to manage.
-Using Garage as your backup target will enable you to scale your storage as needed while ensuring high availability.
-
-## Borg Backup
-
-Borg Backup is very popular among the backup tools but it is not yet compatible with the S3 API.
-We recommend using any other tool listed in this guide because they are all compatible with the S3 API.
-If you still want to use Borg, you can use it with `rclone mount`.

-# Exposing buckets as websites
-
-You can expose your bucket as a website with this simple command:
-
-```bash
-garage bucket website --allow my-website
-```
-
-Now it will be **publicly** exposed on the web endpoint (by default listening on port 3902).
-
-Our website serving logic is as follow:
-  - Supports only static websites (no support for PHP or other languages)
-  - Does not support directory listing
-  - The index is defined in your `garage.toml`. ([ref](/reference_manual/configuration.html#index))
-
-Now we need to infer the URL of your website through your bucket name.
-Let assume:
-  - we set `root_domain = ".web.example.com"` in `garage.toml` ([ref](/reference_manual/configuration.html#root_domain))
-  - our bucket name is `garagehq.deuxfleurs.fr`.
-
-Our bucket will be served if the Host field matches one of these 2 values (the port is ignored):
-
-  - `garagehq.deuxfleurs.fr.web.example.com`: you can dedicate a subdomain to your users (here `web.example.com`).
-
-  - `garagehq.deuxfleurs.fr`: your users can bring their own domain name, they just need to point them to your Garage cluster.
-
-You can try this logic locally, without configuring any DNS, thanks to `curl`:
-
-```bash
-# prepare your test
-echo hello world > /tmp/index.html
-mc cp /tmp/index.html garage/garagehq.deuxfleurs.fr
-
-curl -H 'Host: garagehq.deuxfleurs.fr' http://localhost:3902
-# should print "hello world"
-
-curl -H 'Host: garagehq.deuxfleurs.fr.web.example.com' http://localhost:3902
-# should also print "hello world"
-```
-
-Now that you understand how website logic works on Garage, you can:
-
- - make the website endpoint listens on port 80 (instead of 3902)
- - use iptables to redirect the port 80 to the port 3902:  
-   `iptables -t nat -A PREROUTING -p tcp -dport 80 -j REDIRECT -to-port 3902`
- - or configure a [reverse proxy](reverse_proxy.html) in front of Garage to add TLS (HTTPS), CORS support, etc.
-
-You can also take a look at [Website Integration](/connect/websites.html) to see how you can add Garage to your workflow.

-# Compiling Garage from source
-
-
-Garage is a standard Rust project.
-First, you need `rust` and `cargo`.
-For instance on Debian:
-
-```bash
-sudo apt-get update
-sudo apt-get install -y rustc cargo
-```
-
-You can also use [Rustup](https://rustup.rs/) to setup a Rust toolchain easily.
-
-## Using source from `crates.io`
-
-Garage's source code is published on `crates.io`, Rust's official package repository.
-This means you can simply ask `cargo` to download and build this source code for you:
-
-```bash
-cargo install garage
-```
-
-That's all, `garage` should be in `$HOME/.cargo/bin`.
-
-You can add this folder to your `$PATH` or copy the binary somewhere else on your system.
-For instance:
-
-```bash
-sudo cp $HOME/.cargo/bin/garage /usr/local/bin/garage
-```
-
-
-## Using source from the Gitea repository
-
-The primary location for Garage's source code is the
-[Gitea repository](https://git.deuxfleurs.fr/Deuxfleurs/garage).
-
-Clone the repository and build Garage with the following commands:
-
-```bash
-git clone https://git.deuxfleurs.fr/Deuxfleurs/garage.git
-cd garage
-cargo build
-```
-
-Be careful, as this will make a debug build of Garage, which will be extremely slow!
-To make a release build, invoke `cargo build --release` (this takes much longer).
-
-The binaries built this way are found in `target/{debug,release}/garage`.

-# Cookbook
-
-A cookbook, when you cook, is a collection of recipes.
-Similarly, Garage's cookbook contains a collection of recipes that are known to works well!
-This chapter could also be referred as "Tutorials" or "Best practices".
-
-- **[Multi-node deployment](real_world.md):** This page will walk you through all of the necessary
-  steps to deploy Garage in a real-world setting.
-
-- **[Building from source](from_source.md):** This page explains how to build Garage from
-  source in case a binary is not provided for your architecture, or if you want to
-  hack with us!
-
-- **[Integration with Systemd](systemd.md):** This page explains how to run Garage
-  as a Systemd service (instead of as a Docker container).
-
-- **[Configuring a gateway node](gateways.md):** This page explains how to run a gateway node in a Garage cluster, i.e. a Garage node that doesn't store data but accelerates access to data present on the other nodes.
-
-- **[Hosting a website](exposing_websites.md):** This page explains how to use Garage
-  to host a static website.
-
-- **[Configuring a reverse-proxy](reverse_proxy.md):** This page explains how to configure a reverse-proxy to add TLS support to your S3 api endpoint.
-
-- **[Recovering from failures](recovering.md):** Garage's first selling point is resilience
-  to hardware failures. This section explains how to recover from such a failure in the
-  best possible way.

@@ -1,142 +0,0 @@
-# Configuring a reverse proxy
-
-The main reason to add a reverse proxy in front of Garage is to provide TLS to your users and serve multiple web services on port 443.
-
-In production you will likely need your certificates signed by a certificate authority.
-The most automated way is to use a provider supporting the [ACME protocol](https://datatracker.ietf.org/doc/html/rfc8555) 
-such as [Let's Encrypt](https://letsencrypt.org/), [ZeroSSL](https://zerossl.com/) or [Buypass Go SSL](https://www.buypass.com/ssl/products/acme).
-
-If you are only testing Garage, you can generate a self-signed certificate to follow the documentation:
-
-```bash
-openssl req \
-    -new \
-    -x509 \
-    -keyout /tmp/garage.key \
-    -out /tmp/garage.crt \
-    -nodes  \
-    -subj "/C=XX/ST=XX/L=XX/O=XX/OU=XX/CN=localhost/emailAddress=X@X.XX" \
-    -addext "subjectAltName = DNS:localhost, IP:127.0.0.1"
-
-cat /tmp/garage.key /tmp/garage.crt > /tmp/garage.pem
-```
-
-Be careful as you will need to allow self signed certificates in your client.
-For example, with minio, you must add the `--insecure` flag.
-An example:
-
-```bash
-mc ls --insecure garage/
-```
-
-## socat (only for testing purposes)
-
-If you want to test Garage with a TLS frontend, socat can do it for you in a single command:
-
-```bash
-socat \
-"openssl-listen:443,\
-reuseaddr,\
-fork,\
-verify=0,\
-cert=/tmp/garage.pem" \
-tcp4-connect:localhost:3900
-```
-
-## Nginx
-
-Nginx is a well-known reverse proxy suitable for production.
-We do the configuration in 3 steps: first we define the upstream blocks ("the backends")
-then we define the server blocks ("the frontends") for the S3 endpoint and finally for the web endpoint.
-
-The following configuration blocks can be all put in the same `/etc/nginx/sites-available/garage.conf`.
-To make your configuration active, run `ln -s /etc/nginx/sites-available/garage.conf /etc/nginx/sites-enabled/`.
-If you directly put the instructions in the root `nginx.conf`, keep in mind that these configurations must be enclosed inside a `http { }` block.
-
-And do not forget to reload nginx with `systemctl reload nginx` or `nginx -s reload`.
-
-### Exposing the S3 endpoints
-
-First, we need to tell to nginx how to access our Garage cluster.
-Because we have multiple nodes, we want to leverage all of them by spreading the load.
-In nginx, we can do that with the `upstream` directive.
-
-Then in a `server` directive, we define the vhosts, the TLS certificates and the proxy rule.
-
-A possible configuration:
-
-```nginx
-upstream s3_backend {
-  # if you have a garage instance locally
-  server 127.0.0.1:3900;
-  # you can also put your other instances
-  server 192.168.1.3:3900;
-  # domain names also work
-  server garage1.example.com:3900;
-  # you can assign weights if you have some servers 
-  # that are more powerful than others
-  server garage2.example.com:3900 weight=2;
-}
-
-server {
-  listen [::]:443 http2 ssl;
-
-  ssl_certificate     /tmp/garage.crt;
-  ssl_certificate_key /tmp/garage.key;
-
-  # You need multiple server names here:
-  #  - s3.garage.tld is used for path-based s3 requests
-  #  - *.s3.garage.tld is used for vhost-based s3 requests
-  server_name s3.garage.tld *.s3.garage.tld;
-
-  location / {
-    proxy_pass http://s3_backend;
-    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
-    proxy_set_header Host $host;
-  }
-}
-```
-
-## Exposing the web endpoint
-
-To better understand the logic involved, you can refer to the [Exposing buckets as websites](/cookbook/exposing_websites.html) section.
-Otherwise, the configuration is very similar to the S3 endpoint.
-You must only adapt `upstream` with the web port instead of the s3 port and change the `server_name` and `proxy_pass` entry
-
-A possible configuration:
-
-
-```nginx
-upstream web_backend {
-  server 127.0.0.1:3902;
-  server 192.168.1.3:3902;
-  server garage1.example.com:3902;
-  server garage2.example.com:3902 weight=2;
-}
-
-server {
-  listen [::]:443 http2 ssl;
-
-  ssl_certificate     /tmp/garage.crt;
-  ssl_certificate_key /tmp/garage.key;
-
-  # You need multiple server names here:
-  #  - *.web.garage.tld is used for your users wanting a website without reserving a domain name
-  #  - example.com, my-site.tld, etc. are reserved domain name by your users that chose to host their website as a garage's bucket
-  server_name *.web.garage.tld example.com my-site.tld;
-
-  location / {
-    proxy_pass http://web_backend;
-    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
-    proxy_set_header Host $host;
-  }

-# Data resiliency for everyone
-
-Garage is an **open-source** distributed **storage service** you can **self-host** to fullfill many needs:
-
-<p align="center" style="text-align:center; margin-bottom: 5rem;">
-<img alt="Summary of the possible usages with a related icon: host a website, store media and backup target" src="img/usage.svg" />

-</p>
-
-Garage implements the **[Amazon S3 API](https://docs.aws.amazon.com/AmazonS3/latest/API/Welcome.html)** and thus is already **compatible** with many applications:
-
-<p align="center" style="text-align:center; margin-bottom: 8rem;">
-<img alt="Garage is already compatible with Nextcloud, Mastodon, Matrix Synapse, Cyberduck, RClone and Peertube" src="img/software.svg" />

-
-
-Garage provides **data resiliency** by **replicating** data 3x over **distant** servers:

-## Keeping requirements low
-
-We worked hard to keep requirements as low as possible as we target the largest possible public.
-
-  * **CPU:** any x86\_64 CPU from the last 10 years, ARMv7 or ARMv8.
-  * **RAM:** 1GB
-  * **Disk Space:** at least 16GB
-  * **Network:** 200ms or less, 50 Mbps or more
-  * **Heterogeneous hardware:** build a cluster with whatever second-hand machines are available
-
-*For the network, as we do not use consensus algorithms like Paxos or Raft, Garage is not as latency sensitive.*
-*Thanks to Rust and its zero-cost abstractions, we keep CPU and memory low.*

-
-The following gives details about each available configuration option.
-
-## Available configuration options
-
-#### `metadata_dir`
-
-The directory in which Garage will store its metadata. This contains the node identifier,
-the network configuration and the peer list, the list of buckets and keys as well
-as the index of all objects, object version and object blocks.
-
-Store this folder on a fast SSD drive if possible to maximize Garage's performance.
-
-#### `data_dir`
-
-The directory in which Garage will store the data blocks of objects.
-This folder can be placed on an HDD. The space available for `data_dir`
-should be counted to determine a node's capacity
-when [configuring it](../getting_started/05_cluster.md).
-
-#### `block_size`
-
-Garage splits stored objects in consecutive chunks of size `block_size`
-(except the last one which might be smaller). The default size is 1MB and
-should work in most cases.  If you are interested in tuning this, feel free
-to do so (and remember to report your findings to us!). If this value is
-changed for a running Garage installation, only files newly uploaded will be
-affected. Previously uploaded files will remain available. This however
-means that chunks from existing files will not be deduplicated with chunks
-from newly uploaded files, meaning you might use more storage space that is
-optimally possible.
-
-#### `replication_mode`
-
-Garage supports the following replication modes:
-
-- `none` or `1`: data stored on Garage is stored on a single node. There is no redundancy,
-  and data will be unavailable as soon as one node fails or its network is disconnected.
-  Do not use this for anything else than test deployments.
-
-- `2`: data stored on Garage will be stored on two different nodes, if possible in different
-  zones. Garage tolerates one node failure before losing data. Data should be available
-  read-only when one node is down, but write operations will fail.
-  Use this only if you really have to.
-
-- `3`: data stored on Garage will be stored on three different nodes, if possible each in
-  a different zones.
-  Garage tolerates two node failure before losing data. Data should be available
-  read-only when two nodes are down, and writes should be possible if only a single node
-  is down.
-
-Note that in modes `2` and `3`,
-if at least the same number of zones are available, an arbitrary number of failures in 
-any given zone is tolerated as copies of data will be spread over several zones.
-
-**Make sure `replication_mode` is the same in the configuration files of all nodes.
-Never run a Garage cluster where that is not the case.**
-
-Changing the `replication_mode` of a cluster might work (make sure to shut down all nodes
-and changing it everywhere at the time), but is not officially supported.
-
-### `compression_level`
-
-Zstd compression level to use for storing blocks.
-
-Values between `1` (faster compression) and `19` (smaller file) are standard compression
-levels for zstd. From `20` to `22`, compression levels are referred as "ultra" and must be
-used with extra care as it will use lot of memory. A value of `0` will let zstd choose a
-default value (currently `3`). Finally, zstd has also compression designed to be faster
-than default compression levels, they range from `-1` (smaller file) to `-99` (faster 
-compression).
-
-If you do not specify a `compression_level` entry, garage will set it to `1` for you. With
-this parameters, zstd consumes low amount of cpu and should work faster than line speed in
-most situations, while saving some space and intra-cluster
-bandwidth.
-
-If you want to totally deactivate zstd in garage, you can pass the special value `'none'`. No
-zstd related code will be called, your chunks will be stored on disk without any processing.
-
-Compression is done synchronously, setting a value too high will add latency to write queries.
-
-This value can be different between nodes, compression is done by the node which receive the
-API call.
-
-#### `rpc_secret`
-
-Garage uses a secret key that is shared between all nodes of the cluster
-in order to identify these nodes and allow them to communicate together.
-This key should be specified here in the form of a 32-byte hex-encoded
-random string. Such a string can be generated with a command
-such as `openssl rand -hex 32`.
-
-#### `rpc_bind_addr`
-
-The address and port on which to bind for inter-cluster communcations
-(reffered to as RPC for remote procedure calls).
-The port specified here should be the same one that other nodes will used to contact
-the node, even in the case of a NAT: the NAT should be configured to forward the external
-port number to the same internal port nubmer. This means that if you have several nodes running
-behind a NAT, they should each use a different RPC port number.
-
-#### `rpc_public_addr`
-
-The address and port that other nodes need to use to contact this node for
-RPC calls.  **This parameter is optional but recommended.** In case you have
-a NAT that binds the RPC port to a port that is different on your public IP,
-this field might help making it work.
-
-#### `bootstrap_peers`
-
-A list of peer identifiers on which to contact other Garage peers of this cluster.
-These peer identifiers have the following syntax:
-
-```
-<node public key>@<node public IP or hostname>:<port>
-```
-
-In the case where `rpc_public_addr` is correctly specified in the
-configuration file, the full identifier of a node including IP and port can
-be obtained by running `garage node id` and then included directly in the
-`bootstrap_peers` list of other nodes.  Otherwise, only the node's public
-key will be returned by `garage node id` and you will have to add the IP
-yourself.
-
-#### `consul_host` and `consul_service_name`
-
-Garage supports discovering other nodes of the cluster using Consul.
-This works only when nodes are announced in Consul by an orchestrator such as Nomad,
-as Garage is not able to announce itself.
-
-The `consul_host` parameter should be set to the hostname of the Consul server,
-and `consul_service_name` should be set to the service name under which Garage's
-RPC ports are announced.
-
-#### `sled_cache_capacity`
-
-This parameter can be used to tune the capacity of the cache used by
-[sled](https://sled.rs), the database Garage uses internally to store metadata.
-Tune this to fit the RAM you wish to make available to your Garage instance.
-More cache means faster Garage, but the default value (128MB) should be plenty
-for most use cases.
-
-#### `sled_flush_every_ms`
-
-This parameters can be used to tune the flushing interval of sled.
-Increase this if sled is thrashing your SSD, at the risk of losing more data in case
-of a power outage (though this should not matter much as data is replicated on other
-nodes). The default value, 2000ms, should be appropriate for most use cases.
-
-
-## The `[s3_api]` section
-
-#### `api_bind_addr`
-
-The IP and port on which to bind for accepting S3 API calls.
-This endpoint does not suport TLS: a reverse proxy should be used to provide it.
-
-#### `s3_region`
-
-Garage will accept S3 API calls that are targetted to the S3 region defined here.
-API calls targetted to other regions will fail with a AuthorizationHeaderMalformed error
-message that redirects the client to the correct region.
-
-#### `root_domain`
-
-The optionnal suffix to access bucket using vhost-style in addition to path-style request.
-Note path-style requests are always enabled, whether or not vhost-style is configured.
-Configuring vhost-style S3 required a wildcard DNS entry, and possibly a wildcard TLS certificate,
-but might be required by softwares not supporting path-style requests.
-
-If `root_domain` is `s3.garage.eu`, a bucket called `my-bucket` can be interacted with
-using the hostname `my-bucket.s3.garage.eu`.
-
-## The `[s3_web]` section
-
-Garage allows to publish content of buckets as websites. This section configures the
-behaviour of this module.
-
-#### `bind_addr`
-
-The IP and port on which to bind for accepting HTTP requests to buckets configured
-for website access.
-This endpoint does not suport TLS: a reverse proxy should be used to provide it.
-
-#### `root_domain`
-
-The optionnal suffix appended to bucket names for the corresponding HTTP Host.
-
-For instance, if `root_domain` is `web.garage.eu`, a bucket called `deuxfleurs.fr`
-will be accessible either with hostname `deuxfleurs.fr.web.garage.eu`
-or with hostname `deuxfleurs.fr`.
-
-#### `index`
-
-The name of the index file to return for requests ending with `/` (usually `index.html`).

+## Testing Garage
+
+Currently, we have the following tests:
+
+- some unit tests spread around the codebase
+- integration tests written in Rust (`src/garage/test`) to check that Garage operations perform correctly
+- integration test for compatibility with external tools (`script/test-smoke.sh`)
+
+We have also tried `minio/mint` but it fails a lot and for now we haven't gotten a lot from it.
+
+In the future:
+
+1. We'd like to have a systematic way of testing with `minio/mint`,
+   it would add value to Garage by providing a compatibility score and reference that can be trusted.
+2. We'd also like to do testing with Jepsen in some way.
+
+## How to instrument Garagae
+
+We should try to test in least invasive ways, i.e. minimize the impact of the testing framework on Garage's source code. This means for example:
+
+- Not abstracting IO/nondeterminism in the source code
+- Not making `garage` a shared library (launch using `execve`, it's perfectly fine)
+
+Instead, we should focus on building a clean outer interface for the `garage` binary,
+for example loading configuration using environnement variables instead of the configuration file if that's helpfull for writing the tests.
+
+There are two reasons for this:
+
+- Keep the soure code clean and focused
+- Test something that is as close as possible as the true garage that will actually be running
+
+Reminder: rules of simplicity, concerning changes to Garage's source code.
+Always question what we are doing.
+Never do anything just because it looks nice or because we "think" it might be usefull at some later point but without knowing precisely why/when.
+Only do things that make perfect sense in the context of what we currently know.

+Misc:
+  - [mutagen](https://github.com/llogiq/mutagen) - mutation testing is a way to assert our test quality by mutating the code and see if the mutation makes the tests fail
+  - [fuzzing](https://rust-fuzz.github.io/book/) - cargo supports fuzzing, it could be a way to test our software reliability in presence of garbage data.
