what is pr in github

A pull request is a feature in GitHub that lets you propose changes to a repository by creating a branch and suggesting changes to that branch. Once you create a pull request, other contributors can review your proposed changes, add review comments, contribute to the pull request discussion, and even add commits to the pull request. By default, in public repositories, any user can submit reviews that approve or request changes to a pull request. Organization owners and repository admins can limit who is able to give approving pull request reviews or request changes. After your pull request has been reviewed, it can be merged into the repository. To create a pull request, you can use GitHub.com, GitHub Desktop, GitHub Codespaces, GitHub Mobile, or GitHub CLI.
