      A dead simple static HOMepage for your servER to keep your services on hand, from a simple yaml configuration file.

    virtualHost = {

      nginx.enable = lib.mkEnableOption "a virtualhost to serve homer through nginx";

      caddy.enable = lib.mkEnableOption "a virtualhost to serve homer through caddy";

      domain = lib.mkOption {

        description = ''

          Domain to use for the virtual host.

          This can be used to change nginx options like

          ```nix

          services.nginx.virtualHosts."$\{config.services.homer.virtualHost.domain}".listen = [ ... ]

          ```

          or

          ```nix

          services.nginx.virtualHosts."example.com".listen = [ ... ]

          ```

        '';

        type = lib.types.str;

      };

    };

    package = lib.mkPackageOption pkgs "homer" { };

    settings = lib.mkOption {

      default = { };

      description = ''

        Settings serialized into `config.yml` before build.

        If left empty, the default configuration shipped with the package will be used instead.

        For more information, see the [official documentation](https://github.com/bastienwirtz/homer/blob/main/docs/configuration.md).

        Note that the full configuration will be written to the nix store as world readable, which may include secrets such as [api-keys](https://github.com/bastienwirtz/homer/blob/main/docs/customservices.md).

        To add files such as icons or backgrounds, you can reference them in line such as

        ```nix

        icon = "$\{./icon.png}";

        ```

        This will add the file to the nix store upon build, referencing it by file path as expected by Homer.
