-Nous hébergeons gratuitement les sites dont l'adresse web ressemble à `monbeausite.deuxfleurs.fr`. Si vous souhaitez votre propre nom de domaine (par exemple `monbeausite.fr`), la location du nom de domaine sera à votre charge (~15-20€/an).
+Nous avons de l'expérience en hébergement de sites fonctionnant avec [Wordpress](https://fr.wordpress.org/). C'est un système de gestion de contenu ([CMS](https://fr.wikipedia.org/wiki/Syst%C3%A8me_de_gestion_de_contenu) en anglais) qui permet de construire et d'administrer un site Internet *facilement et  sans connaissances préalables*. Si Wordpress ne vous convient pas, on peut trouver ensemble une autre solution adaptée à vos besoins et envies.

 ## En conclusion 
 
 Venez chez nous ! On vous fera un havre numérique aux petits oignons. Aider Internet à retrouver sa diversité d'antan, c'est important pour nous. On veut voir des blogs en pagaille, des réseaux sociaux délaissés, des thèmes loufoques et la mort de l'uniformisation graphique.
 
-À terme, on demandera (sans doute) de s'inscrire à l'association pour être hébergé, mais pour le moment c'est gratuit et ouvert à tou.te.s, profitez-en !

 Store pile of bytes in your garage.
 
+## Quickstart on an existing deployment
+
+First, chances are that your garage deployment is secured by TLS.
+All your commands must be prefixed with their certificates.
+I will define an alias once and for all to ease future commands.
+Please adapt the path of the binary and certificates to your installation!
+
+```
+alias grg="/garage/garage --ca-cert /secrets/garage-ca.crt --client-cert /secrets/garage.crt --client-key /secrets/garage.key"
+```
+
+Now we can check that everything is going well by checking our cluster status:
+
+```
+grg status
+```
+
+Don't forget that `help` command and `--help` subcommands can help you anywhere, the CLI tool is self-documented! Two examples:
+
+```
+grg help
+grg bucket allow --help
+```
+
+Fine, now let's create a bucket (we imagine that you want to deploy nextcloud):
+
+```
+grg bucket create nextcloud-bucket
+```
+
+Check that everything went well:
+
+```
+grg bucket list
+grg bucket info nextcloud-bucket
+```
+
+Now we will generate an API key to access this bucket.
+Note that API keys are independent of buckets: one key can access multiple buckets, multiple keys can access one bucket.
+
+Now, let's start by creating a key only for our PHP application:
+
+```
+grg key new --name nextcloud-app-key
+```
+
+You will have the following output (this one is fake, `key_id` and `secret_key` were generated with the openssl CLI tool):
+
+```
+Key { key_id: "GK3515373e4c851ebaad366558", secret_key: "7d37d093435a41f2aab8f13c19ba067d9776c90215f56614adad6ece597dbb34", name: "nextcloud-app-key", name_timestamp: 1603280506694, deleted: false, authorized_buckets: [] }
+```
+
+Check that everything works as intended (be careful, info works only with your key identifier and not with its friendly name!):
+
+```
+grg key list
+grg key info GK3515373e4c851ebaad366558
+```
+
+Now that we have a bucket and a key, we need to give permissions to the key on the bucket!
+
+```
+grg bucket allow --read --write nextcloud-bucket --key GK3515373e4c851ebaad366558
+```
+
+You can check at any times allowed keys on your bucket with:
+
+```
+grg bucket info nextcloud-bucket
+```
+
+Now, let's move to the S3 API!
+We will use the `s3cmd` CLI tool.
+You can install it via your favorite package manager.
+Otherwise, check [their website](https://s3tools.org/s3cmd)
+
+We will configure `s3cmd` with its interactive configuration tool, be careful not all endpoints are implemented!
+Especially, the test run at the end does not work (yet).
+
+```
+$ s3cmd --configure
+
+Enter new values or accept defaults in brackets with Enter.
+Refer to user manual for detailed description of all options.
+
+Access key and Secret key are your identifiers for Amazon S3. Leave them empty for using the env variables.
+Access Key: GK3515373e4c851ebaad366558
+Secret Key: 7d37d093435a41f2aab8f13c19ba067d9776c90215f56614adad6ece597dbb34
+Default Region [US]: garage
+
+Use "s3.amazonaws.com" for S3 Endpoint and not modify it to the target Amazon S3.
+S3 Endpoint [s3.amazonaws.com]: garage.deuxfleurs.fr
+
+Use "%(bucket)s.s3.amazonaws.com" to the target Amazon S3. "%(bucket)s" and "%(location)s" vars can be used
+if the target S3 system supports dns based buckets.
+DNS-style bucket+hostname:port template for accessing a bucket [%(bucket)s.s3.amazonaws.com]: garage.deuxfleurs.fr
+
+Encryption password is used to protect your files from reading
+by unauthorized persons while in transfer to S3
+Encryption password: 
+Path to GPG program [/usr/bin/gpg]: 
+
+When using secure HTTPS protocol all communication with Amazon S3
+servers is protected from 3rd party eavesdropping. This method is
+slower than plain HTTP, and can only be proxied with Python 2.7 or newer
+Use HTTPS protocol [Yes]: 
+
+On some networks all internet access must go through a HTTP proxy.
+Try setting it here if you can't connect to S3 directly
+HTTP Proxy server name: 
+
+New settings:
+  Access Key: GK3515373e4c851ebaad366558
+  Secret Key: 7d37d093435a41f2aab8f13c19ba067d9776c90215f56614adad6ece597dbb34
+  Default Region: garage
+  S3 Endpoint: garage.deuxfleurs.fr
+  DNS-style bucket+hostname:port template for accessing a bucket: garage.deuxfleurs.fr
+  Encryption password: 
+  Path to GPG program: /usr/bin/gpg
+  Use HTTPS protocol: True
+  HTTP Proxy server name: 
+  HTTP Proxy server port: 0
+
+Test access with supplied credentials? [Y/n] n
+
+Save settings? [y/N] y
+Configuration saved to '/home/quentin/.s3cfg'
+```
+
+Now, if everything works, the following commands should work:
+
+```
+echo hello world > hello.txt
+s3cmd put hello.txt s3://nextcloud-bucket
+s3cmd ls s3://nextcloud-bucket
+s3cmd rm s3://nextcloud-bucket/hello.txt
+```
+
+That's all for now!

 --> we should not talk about block. It is the abstraction that manipulate your FS to interact with your hard drive. "Chunk" is probably more appropriate.  Block storage are a class of distributed storage where you expose the abstraction of your hard drive over the network, mainly SATA over ethernet, thinking to SCSI, FiberChannel, and so on
