Webster defines a template as a gauge, pattern, or mold used as a guide to the form of a piece being made. And that is a good basic start to defining what a Headway Template is for you.
A Headway Template is a pre-built website template in the Headway Visual Editor. Unlike WordPress Themes, Headway Templates are customizable with the Headway Visual Editor. In a sense, you can take a Headway Template and make it your own. Mold it to fit your individual needs. Plus, you can take the same Headway Template and use it on different sites to give you a head start in your design process.
