-Replace "AppName" by your application name.
+If you are providing a Nightly variant of your application icon, make sure to name it 
"org.gnome.AppNameDevel.svg" (replace "AppName" by your application name). This way the code above will 
assign the desired icon to each profile.
 
 ### Desktop file handling
 The desktop file name has to match the dbus id, so we need to recreate it based on the profile selected.
