        Clans Features that the module implements support for.

        !!! warning "Important"
            Every ClanModule, that specifies `features = [ "inventory" ]` MUST have at least one role.
            Many modules use `roles/default.nix` which registers the role `default`.

            If you are a clan module author and your module has only one role where you cannot determine the name, then we would like you to follow the convention.
