+AlbumTypes Plugin
+=================
+
+The ``albumtypes`` plugin adds the ability to format and output album types,
+such as "Album", "EP", "Single", etc. List of available type can be found
+`here`_.
+
+To use the ``albumtypes`` plugin, enable it in your configuration
+(see :ref:`using-plugins`). Then, add ``$atypes`` to your path formats as
+desired.
+
+.. _here: https://musicbrainz.org/doc/Release_Group/Type
+
+Configuration
+-------------
+
+To configure the plugin, make a ``albumtypes:`` section in your configuration
+file. The available options are:
+
+- **types**: An ordered list of album type to format mappings. The order of the
+  mappings determines their order in the output. If a mapping is missing or
+  blank, it will not be in the output.
+  Default: ``[]``.
+- **ignore_va**: A list of types that should not be output for Various Artists
+  albums. Useful for not adding redundant information - various artist albums
+  are often compilations.
+  Default: ``[]``.
+- **bracket**: Defines the brackets to enclose each album type in the output.
+  Default: ``'[]'``
+
+Examples
+--------
+Example config::
+
+    albumtypes:
+        types:
+            - ep: 'EP'
