First of all we recommend you to develop both 2 versions, HTML and WordPress, and starting from the HTML version. Why this? For two important reasons, first you not need to create the WordPress version if you already have the HTML template due you need only to insert the skin.css into the WordPress theme and insert the contents, that are the same of the HTML template. So after you completed the HTML version you simple need to copy every page with Hybrid Composer. Second, if you are a good developer, in combination with the awesome documentation, you will be faster to create the design and the contents with the HTML version.
