+===============
 
 [Subsonic](http://www.subsonic.org/pages/index.jsp) in a docker container.
+
+*Usage*
+
+* Build: `docker build -t subsonic .`
+* Run: `docker run -d -v /hostpath/music:/var/music -p 4050:4050 -p 4051:4051 subsonic`
+
+*Persistence*
+
+To make the subsonic database persistent, a file and a dir must be mounted to the host:
+
+* -v /hostpath/subsonic/db:/var/subsonic/db
+* -v /hostpath/subsonic/subsonic.properties:/var/subsonic/subsonic.properties
+
+Both locations must be read/writable by uid 1000.
+
+*TODO*
+
+* Allow specifying UID for subsonic user on the fly
