This is the online home of the book “Mercurial: The Definitive Guide”. It was published in 2009 by O'Reilly Media.
Mercurial is a fast, lightweight source control management system designed for easy and efficient handling of very large distributed projects. My book tells you what it is, why you should care, and how you can use it effectively.
If you like the book, please support the work of the Software Freedom Conservancy (see below) by buying a copy.
I publish the source code for this book as a Mercurial repository. Please feel welcome to clone it, make modifications to your copy, and send me changes. Getting a copy of the source takes just a few seconds if you have Mercurial installed:

The online version of the book includes a comment system that you can use to send feedback involving errors, omissions, and suggestions.
