    Add some information to README
    
    Dealing with an application as a service during developement

+gnome-software is split into a service, gnome-software-service, and
+a launcher, gnome-software. Normally, the service is autostarted at
+login to monitor available updates, and the laucher will simply call 
+into the service and cause it to open a window.
+
+During development, you can kill the currently running instance of
+the service, and lauch your version manually:
+
+  killall gnome-software-service
+  ./src/gnome-software-service
+
+To open a window, you can run the launcher in another terminal, e.g.:
+
+  gnome-software --search fox
