# Merge requests **(FREE)**

Merge requests (MRs) are the way you check source code changes into a branch.
When you open a merge request, you can visualize and collaborate on the code changes before merge.
Merge requests include:

- A description of the request.
- Code changes and inline code reviews.
- Information about CI/CD pipelines.
- A comment section for discussion threads.
- The list of commits.

Merge requests contain tabs at the top of the page to help you navigate to
important parts of the merge request: **Overview**, **Commits**, **Pipelines**, and **Changes**.

To get started, read the [introduction to merge requests](getting_started.md).

## Merge request workflows

For a software developer working in a team:

1. You checkout a new branch, and submit your changes through a merge request.
1. You gather feedback from your team.
1. You work on the implementation optimizing code with [Code Quality reports](code_quality.md).
1. You verify your changes with [Unit test reports](../../../ci/unit_test_reports.md) in GitLab CI/CD.
1. You avoid using dependencies whose license is not compatible with your project with [License Compliance reports](../../compliance/license_compliance/index.md).
1. You request the [approval](approvals/index.md) from your manager.
1. Your manager:
   1. Pushes a commit with their final review.
   1. [Approves the merge request](approvals/index.md).
   1. Sets it to [merge when pipeline succeeds](merge_when_pipeline_succeeds.md).
1. Your changes get deployed to production with [manual actions](../../../ci/yaml/README.md#whenmanual) for GitLab CI/CD.
1. Your implementations were successfully shipped to your customer.

For a web developer writing a webpage for your company's website:

1. You checkout a new branch and submit a new page through a merge request.
1. You gather feedback from your reviewers.
1. You preview your changes with [Review Apps](../../../ci/review_apps/index.md).
1. You request your web designers for their implementation.
1. You request the [approval](approvals/index.md) from your manager.
1. Once approved, your merge request is [squashed and merged](squash_and_merge.md), and [deployed to staging with GitLab Pages](https://about.gitlab.com/blog/2021/02/05/ci-deployment-and-environments/).
1. Your production team [cherry picks](cherry_pick_changes.md) the merge commit into production.
