Mozilla's Mercurial documentation has historically been pretty bad. The documentation on MDN (which I refuse to link to) is horribly disjointed and contains a lot of outdated recommendations. I've made attempts to burn some of it to the ground, but it is just too overwhelming.

I've been casually creating my own Mercurial documentation tailored for Mozillians. It's called Mercurial for Mozillians.

It started as a way to document extensions inside the version-control-tools repository. But, it has since evolved to cover other topics, like how to install Mercurial, how to develop using bookmarks, and how to interact with a unified Firefox repository. The documentation is nowhere near complete. But it already has some very useful content beyond what MDN offers.

I'm not crazy about the idea of having generic Mercurial documentation on a Mozilla domain (this should be part of the official Mercurial documentation). Nor am I crazy about moving content off MDN. I'm sure content will move to its appropriate location later. Until then, enjoy some curated Mercurial documentation!

If you would like to contribute to Mercurial for Mozillians, read the docs.
