+Maintenance packages
+--------------------
+
+Generate keyring package
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+The application provides special plugin which generates keyring package. This plugin heavily depends on ``sign`` group settings, however it is possible to override them. The minimal package can be generated in the following way:
+
+#.
+   Edit configuration:
+
+   .. code-block:: ini
+
+      [keyring]
+      target = keyring_generator
+
+   By default it will use ``sign.key`` as trusted key and all other keys as packagers ones. For all available options refer to :doc:`configuration <configuration>.
+
+#.
+   Create package source files:
+
+   .. code-block:: shell
+
+      sudo -u ahriman ahriman repo-create-keyring
+
+   This command will generate PKGBUILD, revoked and trusted listings and keyring itself and will register the package in database.
+
+#.
+   Build new package as usual:
+
+   .. code-block:: shell
+
+      sudo -u ahriman ahriman package-add aur-clone-keyring --source local --now
+
+   where ``aur-clone`` is your repository name.
+
+This plugin might have some issues, in case of any of them, kindly create `new issue <https://github.com/arcan1s/ahriman/issues/new/choose>`_.
+
+Generate mirrorlist package
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The application provides special plugin which generates mirrorlist package also. It is possible to distribute this package as usual later. The package can be generated in the following way:
+
+#.
+   Edit configuration:
+
+   .. code-block:: ini
+
+      [mirrorlist]
+      target = mirrorlist_generator
+
+      [mirrorlist_generator]
+      servers = https://repo.example.com/$arch
+
+   The ``mirrorlist_generator.servers`` must contain list of available mirrors, the ``$arch`` and ``$repo`` variables are supported. For more options kindly refer to :doc:`configuration <configuration>.
+
+#.
+   Create package source files:
+
+   .. code-block:: shell
+
+      sudo -u ahriman ahriman repo-create-mirrorlist
+
+   This command will generate PKGBUILD and mirrorlist file and will register the package in database.
+
+#.
+   Build new package as usual:
+
+   .. code-block:: shell
+
+      sudo -u ahriman ahriman package-add aur-clone-mirrorlist --source local --now
+
+   where ``aur-clone`` is your repository name.
