[wildfly-dev] Architecture Guides - Which tool(s) should I use?

Hi all, Just looking for some feedback for tools currently being used to achieve something similar to the following. I am looking to produce a couple of different architecture guides for the changes being made for security, in general for both guides I am looking to add a high level digram that shows the security components and the components within the digram should be clickable to link to the appropriate section in the document. One thing I would like in the representations of the components is that they support nesting so for example a box called 'authentication mechanisms' could contain both 'sasl mechanisms' and 'http mechanisms'. Ideally this should be in a git repo so we can accept contributions easily using tools readily available. Regards, Darran Lofthouse.
