Please let me make things clear here.
At the present moment the documentation is yet on its early stage. Free version is a kind of experiment - you suggest, we improve. And we have two answers to your request:
1. If you didn't figure out how to assign elements, please follow this link to get the proper information:
Elements(Note: Useritems 1-5 are universal elements - take them as links and remember that they belong to Header and Footer areas only! Sidebar and Post areas contain the list of different elements, such as Post title).
2. We are soon planning to demonstrate the Divine Elemente (formerly Divine Personal) version full functionality. There you'll find ready-made elements that Divine recognizes from Photoshop to save you time and effort from the manual selection of ALL the elements for each template.
