Every change starts with a pull request.
Code Review
Write better code
On GitHub, lightweight code review tools are built into every pull request. Your team can create review processes that improve the quality of your code and fit neatly into your workflow.
Every change starts with a pull request.
- Start a new feature or propose a change to existing code with a pull request—a base for your team to coordinate details and refine your changes.
- Pull requests are fundamental to how teams review and improve code on GitHub. Evolve projects, propose new features, and discuss implementation details before changing your source code.

On GitHub, conversations happen alongside your code. Leave detailed comments on code syntax and ask questions about structure inline.
Review requests
If you’re on the other side of the code, requesting peer reviews is easy. Add users to your pull request, and they’ll receive a notification letting them know you need their feedback.
Reviews
Save your teammates a few notifications. Bundle your comments into one cohesive review, then specify whether comments are required changes or just suggestions.
You can’t always avoid conflict. Merge pull requests faster by resolving simple merge conflicts on GitHub—no command line necessary.
