After you add changes to a topic branch or fork, you can open a pull request to ask your collaborators or the repository administrator to review your changes before merging them into the project.
Branches are used to propose changes to GitHub projects.
You can create or delete branches directly on GitHub.
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
master branch only contains finished and approved work.
If you've forked a repository and made changes to the fork, you can ask that the upstream repository accept your changes by creating a pull request.
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 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.
