.. confval:: local/data_dir
Path to directory to store local metadata such as libraries and playlists
in.
.. confval:: local/playlists_dir

Usage
=====
If you want use Mopidy to play music you have locally at your machine, you need
to review and maybe change some of the local extension config values. See above
for a complete list. Then you need to generate a local library for your local
music...
.. _generating-a-local-library:
Generating a local library
--------------------------
The command :command:`mopidy local scan` will scan the path set in the
:confval:`local/media_dir` config value for any audio files and build a
library.
To make a local library for your music available for Mopidy:
#. Ensure that the :confval:`local/media_dir` config value points to where your
music is located. Check the current setting by running::
mopidy config
#. Scan your media library.::
mopidy local scan
#. Start Mopidy, find the music library in a client, and play some local music!
Pluggable library support
-------------------------
Local libraries are fully pluggable. What this means is that users may opt to
disable the current default library ``json``, replacing it with a third
party one. When running :command:`mopidy local scan` mopidy will populate
whatever the current active library is with data. Only one library may be
active at a time.
To create a new library provider you must create class that implements the
:class:`~mopidy.backends.local.Libary` interface and install it in the
extension registry under ``local:library``. Any data that the library needs
to store on disc should be stored in :confval:`local/data_dir` using the
library name as part of the filename or directory to avoid any conflicts.
