It's actually really self-explanatory if you go look in the template folder. Copy any existing theme your version of Mysidia came with. Replace css with your own. Replace the html inside the template.tpl with your own html. Examine any existing template's template.tpl files for smarty variables such as {$sidebar},{$document_title},{$document_content}, etc, and make sure to incorporate them in appropriate areas. Basically, it's so self-explanatory, it doesn't need a guide. If you know html/css, you can make a theme in exactly as much time.
