When compiling, more on what to do when you reach the screen you get when pressing “Assign Section Layouts”.
It is unclear to me what the exact next step is.
In the video titled Compiling Your Work Part 2 - Section Types and Section Layouts, around 02:40, he goes over the use of that area of compile.
I found them once, there was a page with a number of videos on how to “Scrivel” 
I would appreciate a link posted here to make finding it easier.
Thank You
UPDATE it took me a little while but I found the link to the Scrivener Tutorial Videos here.
