In 2018, documenting code still feels very artisanal. Most of the work is done manually, and has trouble keeping up with the development pace. It is high time to start mining interesting data directly from the version control system. Precise technical docs, like PHP compilation and directives options; classes diagram and file dependencies help understand the essence of the code base. While high level manual has be written by a human for a human, automated tools prove to be of great help to improve code readability.
