I'm uncertain if we have a Standard for Capitalization of Stuff, so I'm approving this but left a few comments that try to sync up the style of "Finding" throughout. Feel free to ignore if you know that I don't know what I'm talking about. 😉

Approved after pending suggestions are committed (:

thanks all - @dogboat yes Findings should be capitalized whenever used in docs.
