@Ridwan yep as scooby mentioned, all you would need to do is drag a Text widget over in one of the widget areas and you can then add your text or HTML code. Remember you can also add a slider or any type of widget you want inside any of those areas (you’re not limited to just text and html).
If there is a specific part of the homepage that you’re trying to replicate just let me know and I’ll copy/paste the exact text/code they used to create it.
If you’re new to Genesis, most Genesis Child themes will show the blog on the homepage by default, and if you add a widget or some content into one of the Home widget areas, then the Homepage template (as seen in the demo) will automatically be activated and the blog will be removed from the homepage…..you can still access the blog by creating a separate Blog page as mentioned in the Tutorial link – http://appfinite.com/tutorials/how-to-setup-the-home-and-blog-page/
