Actually that’s not correct, Wes created plenty of documentation all throughout the site. I’m guessing you haven’t read the README file located in your theme. It’s always best to actually read the Readme when using a theme, it will explain where the documentation/code snippets can be found.
For Epik tutorials on how the frontpage was created (and other details) take a look at the Epik Forum page at the top, its the highlighted sticky posts – http://appfinite.com/forum/epik-theme-support/ ….There are also some general tutorials in the tutorials link in the menu. This has made the entire process very simple for me and many others.
There is more than enough documentation provided to make the demo. Although, none of that is needed, all you have to do is add widget content inside the widget areas. It’s pretty straightforward just like all Genesis themes. You’re in total control of what you want to be displayed in your site whether you want it to look like the demo or not. You’re not required to duplicate the demo, you can create whatever you want.
Again, this is all mentioned inside the README file.
