I'm a very experienced designer + front-end developer and am now looking to start coding my own WP themes!
I'm curious whats the best resource to begin my journey down that path, considering I have the knowledge stated above and a few months of dedicated time. Are there any top notch ebooks that teach how to install a theme into one of the best frameworks?
What is the most popular framework among the most popular selling themes? (Not counting the ones they made on their own)
