+## Development
+
+With [Nix flakes](https://nixos.wiki/wiki/Flakes) and [direnv](https://direnv.net/) installed and enabled, all the required dependencies are automatically loaded from [`shell.nix`](./shell.nix). Then [cargo-make](https://sagiegurari.github.io/cargo-make/) can be used to build, deploy and lint the code. The available tasks are all described in the [`Makefile.toml`](Makefile.toml) configuration.
