+Spotify Plugin
+==============
+
+The ``deezer`` plugin provides metadata matches for the importer using the
+`Deezer_` `Album`_ and `Track`_ APIs.
+
+.. _Deezer: https://www.deezer.com
+.. _Album: https://developers.deezer.com/api/album
+.. _Track: https://developers.deezer.com/api/track
+
+Why Use This Plugin?
+--------------------
+
+* You're a Beets user.
+* You want to autotag music with metadata from the Deezer API.
+
+Basic Usage
+-----------
+First, enable the ``deezer`` plugin (see :ref:`using-plugins`).
+
+You can enter the URL for an album or song on Deezer at the ``enter Id``
+prompt during import::
+
+    Enter search, enter Id, aBort, eDit, edit Candidates, plaY? i
+    Enter release ID: https://www.deezer.com/en/album/572261
+
+Configuration
+-------------
+Put these options in config.yaml under the ``deezer:`` section:
+
+- **source_weight**: Penalty applied to Spotify matches during import. Set to
+  0.0 to disable.
+  Default: ``0.5``.
+
+Here's an example::
+
+    deezer:
+        source_weight: 0.7
