+file archive.
+
+In contrast to @url{https://mopidy.com/ext/file, Mopidy-File}, Mopidy-Local
+builds an index of archive’s metadata ahead of time, and can thus provide
+additional features like search.
+
+The music metadata is stored in a SQLite database. This lets users to browse
+their music collection by album, artist, composer and performer, and provides
+full-text search capabilities based on SQLite’s FTS modules.  It also notices
+updates via @command{mopidy local scan} while Mopidy is running, so you can
+scan your media library periodically, for example from a cron job.")
