 # bonob
 
-A bridge between sonos and ?
+A sonos SMAPI implementation to allow registering sources of music with sonos.  Currently only a single integration allowing Navidrome to be registered with sonos.
+
+In theory as Navidrome implements the subsonic API, it *may* work with other subsonic api clones.
