We use github + markdown + wiki. Is there anything which offer collaboration on document (documentation to be specific) which allows all team members to edit/comment/iterate the docs?
I like to use [Sphinx](<a href="http://sphinx-doc.org/" rel="nofollow">http://sphinx-doc.org/</a>), stored in the project repository.<p>It uses reStructuredText (which is more extensible than Markdown) and was written for the Python documentation.
