+    Introduction
+    ============
+    ZukeBox is an abstraction for a JukeBox.
+    How this works?
+        In a JukeBox somebody pay and choose a song for play, this way the
+    JukeBox should have default set of songs. ZukeBox has the same idea,
+    except for payment ;) , you can choose a song availble in the server 
+    called ZukeBox Server or send a request for server to play your music, 
+    
+    Thus the clientes should be scan the network and get services availble 
+    in ZukeBox Server.
+    Services availble are:
+        1. Show the songs availble in the ZukeBox Server.
+        2. Play a song availble.
+        3. Play a song sent by a control point.
+    Some services will be availble too throught dbus.service a method for 
+    rescan the default paths and save in the database.
