THIS IS A WORK IN PROGRESS.

This project is based on a 120-ish pages book that I wrote in LaTeX, but never completed and never committed to freeze for a first version. Since I can't eff-ing work something in private until completion, I decided to progressively convert the book to markdown and work in a public repository.

Note that this work is released under CC BY-NC-ND, please be nice.

You can use the issues tracker to submit fixes to typos, suggest that I discuss a particular topic, however keep in mind that this is a personal work written in my own style: I will not necessarily merge changes in tone, style or wording.
