Hi John,
Did you watch the video demo?
https://cgcookie.com/lessons/vonnbot-rigs-3-4-demo
It is the latest video documentation which is all still relevant – although bone collections have now been added instead of the older bone layers.
The only text documentation I have is from the original versions in Blender 2.78 (which is very out of date now)
Is there something that you are struggling with?
