Proposing changes to your work with pull requests

Use a branch to isolate development work without affecting other branches in the repository. Each repository has one default branch, and can have multiple other branches. You can merge a branch into another branch using a pull request.

You can create or delete branches directly on GitHub.

Learn about pull requests and draft pull requests on GitHub. Pull requests communicate changes to a branch in a repository. Once a pull request is opened, you can review changes with collaborators and add follow-up commits.

Pull requests display diffs to compare the changes you made in your topic branch against the base branch that you want to merge your changes into.

Create a pull request to propose and collaborate on changes to a repository. These changes are proposed in a branch, which ensures that the default branch only contains finished and approved work.

You can create a pull request to propose changes you've made to a fork of an upstream repository.

Use query parameters to create custom URLs to open pull requests with pre-populated fields.

You can mark a draft pull request as ready for review or convert a pull request to a draft.

After you create a pull request, you can ask a specific person to review the changes you've proposed. If you're an organization member, you can also request a specific team to review your changes.

After you open a pull request, you can update the head branch, which contains your changes, with any changes that have been made in the base branch.

After a pull request is opened, you can change the base branch to compare the changes in the pull request against a different branch.

You can commit changes on a pull request branch that was created from a fork of your repository with permission from the pull request creator.
