Creating a pull request from a fork

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

Who can use this feature?

Anyone with write access to a repository can create a pull request from a user-owned fork.

If your pull request compares your topic branch with a branch in the upstream repository as the base branch, then your topic branch is also called the "compare branch" of the pull request.

For example:

  • Your topic branch (also known as “feature branch”) is the branch where you’re making your changes in your forked repository (e.g. my-topic-branch).
  • The base branch is the branch in the upstream (central) repository that you want to merge your changes into (e.g. main).
  • The pull request compares the changes proposed by the topic branch (my-topic-branch) with the base branch (main), so my-topic-branch is known as the “compare branch”.

For more information about pull request branches, including examples, see "Creating a pull request."

  1. Navigate to the original repository where you created your fork.

  2. Above the list of files, in the yellow banner, click Compare & pull request to create a pull request for the associated branch.

  6. Type a title and description for your pull request.

  7. On user-owned forks, if you want to allow anyone with push access to the upstream repository to make changes to your pull request, select Allow edits from maintainers.

    Warning: If your fork contains GitHub Actions workflows, the option is Allow edits and access to secrets by maintainers. Allowing edits on a fork's branch that contains GitHub Actions workflows also allows a maintainer to edit the forked repository's workflows, which can potentially reveal values of secrets and grant access to other branches.

  8. To create a pull request that is ready for review, click Create Pull Request. To create a draft pull request, use the drop-down and select Create Draft Pull Request, then click Draft Pull Request. For more information about draft pull requests, see "About pull requests."

Tip: After you create a pull request, you can ask a specific person to review your proposed changes. For more information, see "Requesting a pull request review."
