Gerrit provides web based code review and repository management for the Git version control system.
If you are new to Gerrit, you may read a Quick Introduction directly from the Google-hosted documentation Gerrit web-site:
Gerrit is intended to provide a lightweight framework for reviewing every commit before it is accepted into the code base. Changes are uploaded to Gerrit but don’t actually become a part of the project until they’ve been reviewed and accepted.
Gerrit User Summit and Hackathon is THE event for everything related to the Gerrit Code Review Community.
The Gerrit User Summit is the place where all major Gerrit users annually meet and exchange experiences and practices that foster the community with new and useful ideas.
