The Greyson template features a text banner that'll appear at the top of every page to call attention to your latest news, or include links to new sales, or whatever you like! To add that to your site, create a page within the Side Editor, and within the Page Properties, set the Page Keyword of that page to "bannertext." Then hit Save.
Once you've done that, anything you put into the content of that page will show in the top-of-every-page text banner. We suggest keeping it brief, and leaving out large images.
