New sections in API doc course exploring causes for poor product overviews and getting started tutorials

I added two new sections in my API doc course exploring reasons for poor product overviews and sometimes absent getting started tutorials. I'm still adding to this section but wanted to share the current content. These are all first drafts that I hope to refine a bit with more imagery, proofreading, examples, and other detail, so if you have feedback, let me know in the comments. I'm trying to explore reasons why these two content types often fail or are weak. It's less of a best practices section and more like an analysis about causes.
