Hello,
currently the xwiki documentation runs on several wiki instances and
spaces. Unfortunately it's not structured well too, so it's really very
hard to find required information. It's my experience.
I think something like a Table of Content could help indeed. Probably it
would be fix & dirty solution, but nevertheless a solution.
Please look at the current draft for that page:

Any feedback/help would be appreciated.
Regards,
Roman
