Git


 * See Download from Git if you want to checkout the MediaWiki repository for installation and/or development.

For developing MediaWiki, we're using Git version control system and Gerrit, a web based code review system, facilitating online code reviews for Wikimedia. For MediaWiki core development and Wikimedia-deployed extensions, commits must be reviewed before being merged into the master branch.

 * MediaWiki-specific setup: get developer access and install git-review.

The core can be cloned either through HTTPS (read-only) or using SSH (writable):

To check out an extension, clone the repository with your Git client of choice, or use the command line interface:

There is also a meta repository "mediawiki/extensions.git" where all repositories in the  namespace are tracked as git submodules. To set it up:

If you have developer access, you can participate in the review process, but only core developers can merge changes. Git/Workflow gives a full overview of the Git/Gerrit workflow.
