If you are using the Genesis Responsive Slider here is a quick tutorial on how to get it setup (located in the Tutorials section at the top of the site) – http://appfinite.com/tutorials/how-to-add-the-genesis-responsive-slider/ …..you add featured images to the pages that you want to appear in the slider, and then add those Page ID’s to the Slider settings. If the tutorial link above doesn’t cover everything, then let me know what you need help with.
For the blog posts to appear at the bottom (like the demo) we are using the Genesis Featured Posts widget in the Featured Posts widget area. Take a look at this image to see where this widget is located exactly – http://appfinite.com/img/optimal-widgets.jpg ……I have it set to show 3 posts, and I designed the css to show them horizontally as you can see in the demo.
To create your menu you can take a look at this WP tutorial – http://en.support.wordpress.com/menus/#changing-the-order-of-menu-items-and-creating-sub-menus
If you are still unsure about any of this just let me know.
I do plan to add more tutorials for all themes….so that will be coming sometime in the near future.
