Gerrit is the website where all Wikimedia repositories are stored and proposed code changes to those repositories are reviewed. All code changes that are submitted to Gerrit are reviewed on the Gerrit website before being submitted to ensure they meet acceptable code styling, implementation, and security standards.
All Gerrit users can review contributions. Maintainers have the special rights to approve or reject contributions.
If you are a novice developer, read New Developers. If you know that you will work on MediaWiki core and MediaWiki extensions, read How to become a MediaWiki hacker.
Learn how to contribute to MediaWiki development and how to set up a functioning pre-configured development installation of MediaWiki.
If you are an experienced developer, visit the Developer hub instead.
