PR support

PRs are the heart of collaborative development on GitHub.com. GitHub Copilot steps into this space by helping authors and reviewers save time, clarify changes, and catch issues before code is merged. Whether you’re opening a new PR, reviewing changes, or responding to feedback, GitHub Copilot offers a range of tools to simplify the workflow.
