the steps for arch would be almost identical. the desktop entry specification is a standard that is used by arch as well:

how much it integrates depends on what desktop environment you are using. gnome and kde are using the same desktop files as far as I know. So it should work. Haven't tested it though.

You could also use unity with arch: https://wiki.archlinux.org/index.php/Unity
