Mercurial: the definitive guide

First edition (stable)

The first edition of the book was authored by Bryan O'Sullivan and published by O'Reilly in 2009. An HTML version of the book is available for free.

Second edition (in progress)

Work on the second edition of the book was started in 2015 by Mathias De Maré. The current version can be read online.

We, the Hgbook team, want to bring the book up-to-date and explain new concepts and features that have been added to Mercurial in the past few years. Some of the topics that have already been added are:

• Customizing the output of Mercurial through the use of templates
• Changing history using amend, rebase and histedit
• Scaling Mercurial for large repositories and user bases

We welcome contributions to the Hgbook project on Bitbucket.
