1Forks & Open-Source Contributions — What You'll Learn
Contribute to a project you don't have write access to by forking it, and keep your fork in sync with the upstream repository.
Here's everything this chapter covers, in the order you'll learn it:
- What forking a repository means
- Forking on GitHub
- Cloning your fork locally
- Adding the original repo as an 'upstream' remote
- Creating a contribution branch
- Syncing your fork with upstream changes
- Opening a pull request from your fork back to the original project
- Etiquette for external/open-source contributions
- Reading a project's CONTRIBUTING guidelines

2Working Example
💻 Example: Forks & Open-Source Contributions
Bash
git clone https://github.com/your-username/project.git
cd project
git remote add upstream https://github.com/original-owner/project.git
git fetch upstream
git merge upstream/main3Best Practices & Common Pitfalls
💡 Key things to remember:
- Forking gives you your own copy of a repository you don't own, so you can freely experiment and then propose changes back via a pull request without needing write access to the original.
