The 2 subsections of this page ("Compatible IDEs" and "Usage") are using
the same header level as the title (with "===").

Title underlines should match the length of the title. Unfortunately
docutils only catches underlines that are too short.

Add some missing empty lines after titles.

and how to use the script to generate one.

This is not a portage, as there was no original documentation in the
