GitLab’s Merge Requests are your chance to review code before it enters your project’s main branch. A Merge Request (MR) is a wrapper around a git merge operation that’s accessible within the GitLab web UI. Once you’ve reviewed your code, you can initiate the merge with a single click. Adopting an MR-driven workflow helps you guarantee code quality by creating an expectation that all commits are thoroughly reviewed.
