How do I properly configure a template in MailChimp?

I noticed 10 seconds into the video (https://www.youtube.com/watch?v=VOuBGN4Rl74) that the selected template has 1 editable area. How do I create an editable area in MailChimp. I'm guessing this is why my templates aren't showing up in the drop down.
