Ok so recently i've been looking through the themes on cydia and finding few that i liked. So i decided im going to try to make my own, but im not sure how to start. First off i found some templates that are .rar and im not sure how or what to use to open those. Secondly i have seen people say you need to have your folder called xxxxx.theme i was wondering what .theme is. if you could help me out it would be greatly appreciated, thanks.
