 You may also want to change some of the ``LOCAL_*`` settings. See
 :mod:`mopidy.settings`, for a full list of available settings.

+Generating a tag cache
+----------------------
+
+Previously the local storage backend relied purely on ``tag_cache`` files
+generated by the original MPD server. To remedy this the command
+:command:`mopidy-scan` has been created. The program will scan your current
+:attr:`mopidy.settings.LOCAL_MUSIC_FOLDER` and build a MPD compatible
+``tag_cache``.
+
+To make a ``tag_cache`` of your local music available for Mopidy:
+
+#. Ensure that :attr:`mopidy.settings.LOCAL_MUSIC_FOLDER` points to where your
+   music is located. Check the current setting by running::
+
+    mopidy --list-settings
+
+#. Scan your music library. Currently the command outputs the ``tag_cache`` to
+   ``stdout``, which means that you will need to redirect the output to a file
+   yourself::
+
+    mopidy-scan > tag_cache
+
+#. Move the ``tag_cache`` file to the location
+   :attr:`mopidy.settings.LOCAL_TAG_CACHE` is set to, or change the setting to
+   point to where your ``tag_cache`` file is.
+
+#. Start Mopidy, find the music library in a client, and play some local music!
