Upfront editing the template page

I'd like to start by editing the template page as seen on your web site rather than creating a whole new one from scratch. Once I installed Fixer and click upfront in the top, it opens up your template page but that isn't actually listed in the wordpress dashboard as a page or post. How can I copy it or add it to a wordpress page? or is the theme supposed to only work as it is without creating more pages?
