The presentation page also comes equipped with 3 text areas and an infinite number of columns. The text areas are positioned above and below the columns and blog posts. They support HTML tags (including images) and [shortcodes] so you can turn the Presentation Page into your personal playground.
Just like everything else on the Presentation Page you can choose whether to use these text areas or not. You can edit them from
Theme Settings » Presentation Page Settings » Text Areas.
