# Pull Requests & Code Review

## Overview

The code review process is oriented around pull requests. A pull request (or "PR") is opened when a contributor to a repository is requesting a reviewer to "pull" their code changes into their repository.

Put more simply, a pull request is a request for code review. It is a convention that has been built up over time, and it's ubiquitously supported by platforms like GitHub, GitLab, and of course, Copia.

Typically, the code review process involves contributors and reviewers. "Contributors" refer to developers who have made changes and are requesting a review, while "Reviewers" are the individuals or teams who perform a review and approve changes.
