Pull Request
A proposed change to a project that maintainers can review before merging it in.
A pull request, often shortened to PR, is the standard way to propose a change to an open-source project you do not control directly. You copy the project (a fork), make your change on a branch, then open a pull request asking the maintainers to review and merge it. The PR becomes a public discussion: maintainers leave comments, you respond and refine, and once everyone is satisfied the change is merged into the main project. Pull requests keep an open-source project safe by ensuring every change is reviewed before it lands, and they keep a permanent record of who changed what and why. Your first PR is usually small, such as a documentation fix.
