When working with multiple contributors on a GitHub repository, forks are an essential feature to understand. Forking allows you to create a copy of a repository under your GitHub account, giving you the freedom to make changes without affecting the original project.
GitHub forks have become a popular way of collaborating on open-source projects, as they allow developers to propose changes and improvements without directly altering the original codebase. This enables easy experimentation and fosters a collaborative environment where developers can work on their own versions before suggesting modifications to the original repository.
Creating a fork on GitHub is simple. Once you find a repository you want to contribute to, navigate to the repository’s page and click the “Fork” button located at the top-right corner of the page. This action creates a forked copy of the repository under your GitHub account, which you can later clone and work on locally.
Working with forks involves a two-step process: creating a fork, and then submitting your changes back to the original repository through a pull request. This workflow allows repository owners to review and approve changes before merging them into the main project. It also ensures that the original codebase remains intact while incorporating valuable contributions from other developers.
Overall, forks are an integral part of the GitHub ecosystem, providing developers with the flexibility and collaboration tools needed to contribute to open-source projects effectively. By understanding how to work with forks, you can join the vibrant community of developers and make meaningful contributions to the projects you care about.
What is a fork?
A fork in the context of GitHub is a copy of a repository that allows you to freely experiment with changes without affecting the original project. When you fork a repository, you create your own personal copy of it under your GitHub account. This allows you to make changes to the code, either for personal use or to propose changes back to the original repository.
Essentially, a fork creates a separate version of the project that you can modify and update independently from the original repository. This is especially useful when you want to contribute to a project, but you don’t have permission to directly edit the original.
Why would you fork a repository?
There are several reasons why you may want to fork a repository:
- Contribute to an open-source project: Forking a repository allows you to make changes to the code and propose these changes to the original repository.
- Create your own version of a project: Forking allows you to take an existing project and modify it to suit your own needs or preferences. This can be useful if you want to use a project as a starting point for your own work.
- Experiment with changes: Forking provides a safe environment to experiment with changes without affecting the original repository. This allows you to test new features or fixes before proposing them to the original project.
By forking a repository, you create a separate copy that you have full control over. This allows you to freely explore and modify the project without any limitations.
Why would you fork a repository?
Forking a repository on GitHub is a common practice among developers for several reasons:
1. Contributing to an existing project
When you fork a repository, you create a personal copy of it on your GitHub account. This allows you to freely experiment with the code, make changes, and add new features without affecting the original project. You can then submit a pull request to the original repository owner to propose your changes for review and possible incorporation into the main project.
This is particularly useful for open-source projects where collaboration and community contributions are encouraged. By forking a repository, you can work on your own version of the project and contribute back to the community.
2. Building upon an existing project
Forking also enables you to build upon an existing project and extend its functionalities to suit your own needs. It provides a starting point for your own development efforts, saving you time and effort in designing and implementing the basic infrastructure. You can customize the code to add new features, fix bugs, or optimize performance according to your specific requirements.
This is especially beneficial for developers who want to use an existing project as a foundation for their own projects, allowing them to leverage the work that has already been done.
A forked repository serves as an independent entity, in which you have full control. You can further modify, experiment, and collaborate with others on your fork without impacting the original project.
3. Preserving the state of a project
Forking also helps safeguard the state of a project at a particular point in time. By creating a fork, you create a snapshot of the codebase as it exists at that moment. This can be useful if you want to preserve a specific version of the code for reference or future use.
Additionally, if the original repository undergoes significant changes or is deleted, your fork remains intact, enabling you to continue working on the codebase independently.

|---|
| 1. Contribute to an existing project |
| 2. Build upon an existing project |

How to create a fork on GitHub
GitHub is a powerful platform for collaborative software development, allowing developers to contribute to projects and share their code. One of the key features of GitHub is the ability to create a fork, which is a personal copy of another user’s repository. This allows you to freely experiment with the code, make changes, and propose them to the original repository owner.
Here are the steps to create a fork on GitHub:
- Sign in to your GitHub account: Before creating a fork, you need to have a GitHub account and be logged in.
- Navigate to the repository: Go to the repository you want to fork by searching for it or using a direct link.
- Click the “Fork” button: Once you’re on the repository page, click the “Fork” button in the top-right corner of the page. This will create a copy of the repository in your GitHub account.
- Wait for the fork to complete: GitHub will process the fork request, which may take a few moments. Once the process is complete, you will be redirected to your forked repository page.
Note: The forked repository will be completely independent from the original repository, meaning any changes you make to the forked repository won’t affect the original. This allows you to experiment, make changes, and propose them to the original repository owner without modifying the original codebase.
Now you know how to create a fork on GitHub. Happy forking!
How to keep your fork synced with the original repository
When you create a fork of a repository on GitHub, it’s important to keep your fork up to date with any changes made to the original repository. This ensures that you have the latest updates and bug fixes.
Here are the steps to keep your fork synced:
1. Adding the original repository as a remote
First, you need to add the original repository as a remote in your local repository. Open the terminal and navigate to the directory of your local repository. Then, enter the following command:
git remote add upstream https://github.com/original-repository-owner/original-repository.git
This will add the original repository as a remote named “upstream” to your local repository.
2. Fetching and merging the changes
Next, you need to fetch the changes from the original repository and merge them into your fork. Run the following commands:
git fetch upstream
git merge upstream/master
This will fetch the changes from the original repository and merge them into the local master branch.
3. Pushing the changes to your fork
Finally, you need to push the changes to your fork on GitHub. Run the following command:
git push origin master
This will push the changes to your fork on GitHub, keeping it synced with the original repository.
By following these steps regularly, you can easily keep your fork up to date and benefit from any updates made to the original repository.
Contributing to the original repository from your fork
When you have made changes in your forked repository and want to contribute those changes to the original repository, you can do so by creating a pull request. This allows the owner of the original repository to review your changes and potentially merge them into the main branch.
To create a pull request, follow these steps:
1. Sync your forked repository with the original repository
Before creating a pull request, it’s important to ensure that your forked repository is up to date with the latest changes from the original repository. This can be done by syncing your fork.
To sync your fork with the original repository, you can follow these steps:
- Navigate to the main page of your forked repository on GitHub.
- Click on the “Fetch upstream” or “Fetch origin” button, depending on the version control system you are using.
- Review the changes and resolve any conflicts if necessary.
- Commit the changes and push them to your forked repository.
2. Create a new branch
Before making any changes to the code, it’s a good practice to create a new branch. This allows you to work on a separate branch and keeps your changes isolated from the main branch.
To create a new branch, follow these steps:
- Open your forked repository in your version control system or editor.
- Create a new branch with a descriptive name that reflects the changes you are working on.
- Switch to the new branch.
3. Make and commit your changes
Once you have created a new branch, you can make the desired changes to the code. It’s important to make small, focused commits with descriptive commit messages.
After making the changes, commit them to the new branch by following these steps:
- Add the changed files to the staging area.
- Create a commit with a descriptive message that explains the changes.
- Push the commit to your forked repository.
4. Create a pull request
After committing your changes to the new branch, you can create a pull request to propose those changes to the owner of the original repository.
To create a pull request, follow these steps:
- Navigate to the main page of your forked repository on GitHub.
- Click on the “New pull request” button.
- Choose the branch with your changes as the base branch.
- Select the main branch of the original repository as the compare branch.
- Review the changes and provide a descriptive title and comment.
- Click on the “Create pull request” button to submit your pull request.
Once your pull request is created, the owner of the original repository will be notified. They will review your changes and provide feedback if necessary. If your changes are deemed suitable, they can merge them into the main branch of the original repository.
Contributing to the original repository from your fork is a collaborative process that allows you to share your improvements with the community and contribute to open-source projects.
