Most people will agree documentation is hard and painful. Engineers like to build and have someone else maintain and support. Im talking in generalities - so don't get too offended if thats not you.
So it follows that you should reduce the critical path to documentation down to the path of least resistance. Markdown tools are plentiful. If you use GitHub, it is the core of their project management tools.
Also, you want documentation to be a "living & breathing document" - in the sense that it should be updated and modifiable by everyone. A LaTeX-like solution doesn't lend itself easily to collaborative work.
