+MusicBrainz Submit Plugin
+=========================
+
+The ``mbsubmit`` plugin provides an extra prompt choice during an import
+session that prints the tracks of the current album in a format that is
+parseable by MusicBrainz's `track parser`_.
+
+.. _track parser: http://wiki.musicbrainz.org/History:How_To_Parse_Track_Listings
+
+Usage
+-----
+
+Enable the ``mbsubmit`` plugin in your configuration (see :ref:`using-plugins`)
+and select the ``Print tracks`` choice which is by default displayed when no
+strong recommendations are found for the album::
+
+    No matching release found for 3 tracks.

+    Print tracks?
+
+As MusicBrainz currently does not support submitting albums programmatically,
+the recommended workflow is to copy the output of the ``Print tracks`` choice
+and paste it into the parser that can be found by clicking on the
+"`Track Parser`" button on MusicBrainz "`Tracklist`" tab.
+
+Configuration
+-------------
+
+To configure the plugin, make a ``mbsubmit:`` section in your configuration
+file. The following options are available:
+
+- **mb_format**: The format used for printing the tracks, defined using the
+  same template syntax as beets’ :doc:`path formats </reference/pathformat>`.
+  Default: ``$track. $title - $artist ($length)``.
+- **threshold**: The minimum strength of the autotagger recommendation that
+  will cause the ``Print tracks`` choice to be displayed on the prompt.
+  Default: ``medium`` (causing the choice to be displayed for all albums that
+  have a recommendation of medium strength or lower). Valid values: ``none``,
+  ``low``, ``medium``, ``strong``.
+
+Please note that some values of the ``threshold`` configuration option might
+require other ``beets`` command line switches to be enabled in order to work as
+intended. In particular, setting a threshold of ``strong`` will only display
+the prompt if ``timid`` mode is enabled. You can find more information about
+how the recommendation system works on :ref:`match-config`.
