# Continuwuity for NixOS

## Nix package

You can get a Nix package for Continuwuity from the following sources:

- Directly from Nixpkgs: `pkgs.matrix-continuwuity`
- Or, using `continuwuity.packages.${system}.default` from:
    - The `flake.nix` at the root of the Continuwuity repo, by adding Continuwuity to your flake inputs:

    ```nix
    inputs.continuwuity.url = "git+https://forgejo.ellis.link/continuwuation/continuwuity";
    ```

    - The `default.nix` at the root of the Continuwuity repo

## NixOS module

Continuwuity has an official NixOS module that simplifies configuration and deployment. The module is available in Nixpkgs as `services.matrix-continuwuity`.

Here's a basic example of how to use the module:

```nix
services.matrix-continuwuity = {
  enable = true;
  settings = {
    global = {
      server_name = "example.com";

      # Continuwuity listens on localhost by default,
      # address and port are handled automatically

      # You can add any further configuration here, e.g.
	  # trusted_servers = [ "matrix.org" ];
    };
  };
};
```

### Available options

The NixOS module provides these configuration options:

- `enable`: Enable the Continuwuity service
- `user`: The user to run Continuwuity as (defaults to "continuwuity")
- `group`: The group to run Continuwuity as (defaults to "continuwuity")
- `extraEnvironment`: Extra environment variables to pass to the Continuwuity server
- `package`: The Continuwuity package to use, defaults to `pkgs.matrix-continuwuity`
    - You may want to override this to be from our flake, for faster updates and unstable versions:
    ```nix
    package = inputs.continuwuity.packages.${pkgs.stdenv.hostPlatform.system}.default;
    ```
- `admin.enable`: Whether to add the `conduwuit` binary to `PATH` for administration (enabled by default)
- `settings`: The Continuwuity configuration

Use the `settings` option to configure Continuwuity itself. See the [example configuration file](../reference/config.mdx) for all available options.

Settings are automatically translated from Nix to TOML. For example, the following line of Nix:

```nix
settings.global.well_known.client = "https://matrix.example.com";
```

Would become this equivalent TOML configuration:

```toml
[global.well_known]
client = "https://matrix.example.com"
```

## Reverse proxy configuration

You'll need to set up a reverse proxy (like NGINX or Caddy) to expose Continuwuity to the internet. You can configure your reverse proxy using NixOS options (e.g. `services.caddy`).
See the [reverse proxy setup guide](./generic.mdx#setting-up-the-reverse-proxy) for information on correct reverse proxy configuration.
