I use this repository to source control documents I generate from working with WebSphere Application Server (WAS). I have quite a backlog of topics to document. My plan is to document small focused topics at a time. This way I can combine them as needed into larger topics or standalone.
Renderings are available on the pages site.
I enter the document source in DocBook format and render the output using DocBook stylesheets. You do not have to understand DocBook to review content or even to suggest changes. The XML input files for DocBook are easy to understand when you see one. But if you wish to render DocBook output yourself, I would suggest an Eclipse-based set-up. However, there are many other ways of setting up your own DocBook environment documented in the DocBook Complete Guide.
