As I mention in this post - [Roadmap] Path to v9 - #8 by James_Robertson - the pull request process does not force the docs to keep up with code changes. So right now the docs are in an interesting state of some v6, some v7 and some v8, especially where screen shots are concerned.
I think that the frappe team is looking at a documentation update or something, not sure though. I also suggested that docs be pulled out and into a separate repository. Might make management easier. I personally could help more there if there was a better build system for windows.
