First you go to this site:
http://www.swiftkit.net/Then you click on free download above where it says current active users.
Then you click the red button that says download.
Now you save the file, and then wait till its downloaded (Should have a list of downloads)
Then double click it when its finished and it should have a shortcut on your wallpaper spot thing!
^It should tell you what to do.
Now you have all that stuff it checked where it said "Free download" in the b0x.
Now pl0x in a b0x download it!
