Edit2: you have to unziping the folder and poof u got RC...

Edit1: "tgz" is a "zip" file
Edir3: "sudo" is just a command to get root access, such as "run as administrator", it should only be used when doing things that requires rights that a normal user don't get to have, such as if ur going to edit/add/remove something outside of '/home/'
