New Tab Studio Theme Creation Tutorial or Guide?

Perhaps a New Tab Studio Theme Creation Tutorial, Guide or How-To exists but I could not find it one anywhere. I would like to create my very own New Tab Studio Themes (and of course share some of them in the User Themes Section of the New Tab Studio Website too). Does a New Tab Studio Theme Creation Tutorial, Guide or How-To currently exist and if so, where can I find it? If not, can someone write and post one for those of us that want to Create Themes for New Tab Studio, please or point us in the right direction for creating Themes for New Tab Studio?

ANY & ALL HELP WOULD BE GREATLY APPRECIATED. PLEASE LET ME KNOW WHERE I CAN FIND A TUTORIAL, GUIDE OR HOW-TO OR POINT ME IN THE CORRECT DIRECTION SO I CAN START CREATING AND SHARING MY OWN TGEMES FOR NEW TAB STUDIO PLEASE.
