-## Build
+# CryptPad for NixOS with Deuxfleurs flavour
 
-Cryptpad being not NixOS native, an upgrade must be done in 4 steps:
+## Building
-  1. Bump the cryptpad version in `common.nix`
-  2. Rebuild the Nix lock files for the dependencies 
-  3. Build the package for Nix
-  4. Create a container from the Nix package
 
-To bump the nix version, set the desired tag in `common.nix` in the `cryptpadVersion` entry.
+The `default.nix` file follows the nixpkgs `callPackage` convention for fetching dependencies, so you need to either:
-Set the corresponding commit in the `cryptadCommit` field, its goal would be to detect unwanted update of the tag.
 
-To rebuild the lock files (they are stored in the `nix.lock` folder):
+- Run `nix-build --expr '{ ... }@args: (import <nixpkgs> {}).callPackage ./default.nix args'`
+- Do the `callPackage from a higher-level directory importing your package`
 
-```
+### Docker
-nix-shell --run "update_lock"
+
+The `docker.nix` derives into a Docker image you can load simply by running:
+
+```shell
+docker load -i $(nix-build docker.nix)
 ```
 
-To build cryptpad:
+You can then test the built Docker image using the provided `docker-compose.yml` and `config.js` files, which are
+configured to render the instance accessible at `http://localhost:3000` with data stored into the `_data` folder.
 
-```
+
-nix-build
+### Deuxfleurs flavour
+The `deuxfleurs.nix` file derives into two derivations: The CryptPad derivation itself and a Docker image,
+which can be choose by passing the `-A [name]` flags to `nix-build`
+
+For example, to build and load the Deuxfleurs-flavoured CryptPad Docker image, you run:
+
+```shell
+docker load -i $(nix-build deuxfleurs.nix -A docker)
 ```
 
-Create the container:
+## OnlyOffice integration
+Apart for `deuxfleurs.nix`, both `default.nix` and `docker.nix` files build CryptPad with a copy of OnlyOffice pre-built and
+used by CryptPad, which can result to large Docker image (~2.6GiB)
 
+This behaviour is configurable by passing the `--arg withOnlyOffice false` flag to `nix-build` when building them.
+
+## Updating the Deuxfleurs pinned nixpkgs
+The pinned sources files are generated with the [niv](https://github.com/nmattia/niv) tool.
+
+To update the pinned nixpkgs, you simply run the following command:
+
+```shell
+niv update
 ```
-docker load < $(nix-build docker.nix)
+
-docker push superboum/cryptpad:???
+To modify the pinned nixpkgs, you can use the `niv modify` command, for example, to move to nixpkgs-unstable:
+
+```shell
+niv modify nixpkgs -b nixos-unstable
 ```
+
+## Quirks
+
+- The CryptPad `package-lock.json` is included here because the upstream-provided one appeared to be desync'ed, so a
+    manual lockfile generation was needed
