What Is a Pull Request?
A pull request — or PR — is a proposal to merge your changes into a project. It’s the heart of collaboration on GitHub: you push a branch, open a PR, and reviewers can comment, approve, or request changes before it’s merged.
Why PRs matter
- They make every change reviewable.
- They’re how open-source contributions happen — you fork, change, and PR back.
- They keep the main branch clean and stable.
If you understand PRs, you understand how the world’s software gets built together.
