Each text file under Documentation follows a different format. Some doesn't even have titles! Change its representation to follow the adopted standard, using ReST markups for it to be parseable by Sphinx: This file is almost in the right format. It only needed to convert a list to bulleted list and to use the right markup for literal blocks.
