There are a ton of videos on using X-Theme Pro... none I've found start at the beginning

Brand new, absolutely totally novice user here. I bought the goods that X-Theme / Pro is the easiest and best way to create a simple consulting website.

So how do I start? I’ve got a blank canvas. I’ve reviewed lots of the Cornerstone videos, and EVERY SINGLE ONE starts with the speaker going to a page that is already created, and then describes how to to use Cornerstone to modify it.

But I don’t have any pages already created. I want to create an initial site based on a combination of elements in some of the beautiful (albeit incredibly limited) templates. No clue how do to that. And nothing I’ve found in the documents takes a novice user from blank canvas to initial site created based on one of the provided templates.
