 mopidy is a MPD server with a Spotify backend.
 
 
+Goal
+----
+
+Using a standard MPD client we want to search for music in Spotify, manage
+Spotify play lists and play music from Spotify.
+
+To limit scope, we will start by implementing a MPD server which only supports
+Spotify, and not playback of files from disk. We will make mopidy modular, so
+we can extend it with other backends in the future, like file playback and
+other online music services such as Last.fm.
