+Setup
+=====
+
+1.	You'll need to save your auth credentials to ~/.libre.fm-cmus.auth:
+
+		unset HISTFILE
+		coffee -e "require('./auth.coffee').save_auth 'USERNAME','PASSWORD'"
+
+	(Substituting your libre.fm username and password of course.) The first
+	line disables history saving in bash, and perhaps other shells.
