I just downloaded the Adobe Reader app for my IPad. Fortunately, it's full of nice useful-looking icons. Unfortunately, I can't figure out what they all do. I have several "how do I do this" questions. I would be happy to just read the documentation -- but I haven't found any. I found the faq at https://helpx.adobe.com/acrobat/mobile-app-faq.html, but the faq is very general and goes into little detail. Also, the faq does not seem to point to any actual documentation.
