      A mod installer, creator and manager for all your popular games.

      Currently experimental and undergoing active development,
      new releases may include breaking changes!

            It is strongly recommended that you use the "unfree" variant of this package,
            which provides support for mods packaged as RAR archives.

            You can also enable unrar support manually, by overriding the `_7zz` used:

            ```nix
            pkgs.nexusmods-app.override {
              _7zz = pkgs._7zz-rar;
            }
            ```
          ''
      }
    '';
  };
})
