How to Fork the OSSU Computer Science Repository: A Complete Guide

Forking the OSSU computer science repository creates a personal copy under your GitHub account, allowing you to track curriculum progress, experiment with modifications, and submit contributions back to the upstream project.

The Open Source Society University (OSSU) maintains its comprehensive computer science curriculum on GitHub at github.com/ossu/computer-science. When you fork the OSSU computer science repository, you establish an independent workspace that mirrors the entire project history, branches, and file structure while maintaining a connection to the original source for future updates.

Why Fork the OSSU Computer Science Repository?

Creating a fork serves multiple practical purposes for learners and contributors. The repository's own README.md explicitly recommends forking as the primary method to track your progress through the curriculum, enabling you to mark completed courses and add personal notes directly in your copy.

Additionally, forking allows you to:

• Experiment safely with modifications to course schedules or resource links without affecting the canonical curriculum
• Submit contributions such as typo fixes, resource updates, or curriculum improvements via pull requests
• Maintain version control of your personal learning journey alongside the evolving upstream content

Step-by-Step Guide to Fork the OSSU Computer Science Repository

Navigate to the Repository

Open your web browser and navigate to the official repository URL:

https://github.com/ossu/computer-science

This page contains the main curriculum files, including the README.md that provides the fork instructions referenced throughout the community.

Create Your Fork

Locate the "Fork" button in the upper-right corner of the repository page, positioned between the "Watch" and "Star" buttons. Click this button to initiate the forking process.

GitHub will present a dialog prompting you to select the destination account or organization. Choose your personal GitHub account (or an organization where you have appropriate permissions). GitHub will then create a new repository named computer-science under your selected account.

Verify Your Fork

Once the process completes, your browser will redirect to your new fork URL:

https://github.com/<YOUR_USERNAME>/computer-science

Verify that the repository header displays "forked from ossu/computer-science" beneath the repository name, confirming the upstream relationship. Your fork now contains identical content to the original, including all branches, commit history, and files such as CONTRIBUTING.md and the .github/workflows/ directory.

Working with Your Fork: Essential Git Workflows

After forking, you'll need to clone the repository locally and configure it for ongoing use. The following workflows assume you have Git installed on your local machine.

Clone Your Fork Locally

Open your terminal and clone your fork to create a local working copy:

# Clone your fork to a local machine

git clone https://github.com/<YOUR_USERNAME>/computer-science.git
cd computer-science

Replace <YOUR_USERNAME> with your actual GitHub username. This command downloads the entire repository history, including the coursepages/ directory containing course-specific resources.

Configure Upstream Remote

To keep your fork synchronized with the original OSSU repository, add the upstream remote:

# Add the upstream OSSU repo as a remote

git remote add upstream https://github.com/ossu/computer-science.git

Verify the configuration:

git remote -v

You should see both origin (pointing to your fork) and upstream (pointing to ossu/computer-science).

Sync with Upstream Changes

Periodically update your fork to incorporate changes from the main OSSU repository:

# Fetch upstream changes

git fetch upstream

# Checkout your main branch

git checkout main

# Merge upstream changes into your fork

git merge upstream/main

# Push updated main branch to your fork

git push origin main

This workflow ensures your local copy includes the latest curriculum updates, bug fixes in .github/workflows/delete-empty-issues.yml, or changes to CONTRIBUTING.md.

Track Progress and Contribute

Use branches to track your personal progress or prepare contributions:

# Create a new branch for tracking progress

git checkout -b my-progress

# Make changes (e.g., mark completed courses in README)

git add .
git commit -m "Add progress marker for Algorithms course"

# Push branch to your fork

git push origin my-progress

To contribute changes back to OSSU, open a Pull Request via the GitHub web interface, selecting your branch as the compare branch and ossu/computer-science:main as the base.

Key Files in the OSSU Repository

Understanding the repository structure helps you navigate your fork effectively:

• README.md – The central curriculum hub containing course listings, prerequisites, and the official fork instructions referenced throughout the community.
• CONTRIBUTING.md – Guidelines for submitting improvements, essential reading if you plan to open pull requests from your fork.
• .github/workflows/delete-empty-issues.yml – Example GitHub Actions configuration demonstrating that forks retain automation workflows from the original repository.
• coursepages/ – Directory containing detailed course-specific README files and resources for each subject in the curriculum.

Summary

• Forking the OSSU computer science repository creates a personal GitHub copy at github.com/<YOUR_USERNAME>/computer-science while maintaining an upstream link to ossu/computer-science.
• The Fork button in the upper-right corner of the repository page initiates the process, which the README.md explicitly recommends for tracking curriculum progress.
• After forking, clone locally, add an upstream remote, and periodically sync with git fetch upstream to incorporate curriculum updates.
• Use branches to track personal progress or prepare contributions, following guidelines in CONTRIBUTING.md when submitting pull requests.

Frequently Asked Questions

How do I keep my fork of the OSSU computer science repository updated with the latest curriculum changes?

Configure an upstream remote pointing to https://github.com/ossu/computer-science.git, then periodically run git fetch upstream, checkout your main branch, and execute git merge upstream/main followed by git push origin main. This workflow ensures your personal copy includes the latest updates to course listings in README.md and resources in the coursepages/ directory.

Can I use my fork to track which OSSU courses I've completed?

Yes, forking is the recommended method for progress tracking according to the repository's README.md. After creating your fork, you can edit the README.md file in your personal copy to mark completed courses, add completion dates, or include personal notes. Commit these changes to a dedicated branch such as my-progress to maintain a clear history of your academic journey through the curriculum.

What is the difference between forking and cloning the OSSU repository?

Forking creates a copy of the repository under your GitHub account on GitHub's servers, establishing a persistent relationship with the upstream ossu/computer-science repository that enables pull requests and synchronization. Cloning merely downloads a copy of a repository (either the original or your fork) to your local machine for editing. To contribute to OSSU or maintain a personal progress tracker, you should first fork the repository on GitHub, then clone your fork locally using git clone https://github.com/<YOUR_USERNAME>/computer-science.git.

Do I need special permissions to fork the OSSU computer science repository?

No, forking requires no special permissions because the OSSU computer science repository is publicly available under an open-source license. Any GitHub user can click the Fork button in the upper-right corner of the repository page to create a personal copy. However, if you wish to contribute changes back to the upstream repository via pull requests, you should review the CONTRIBUTING.md file in your fork for guidelines on submission standards and commit message conventions.
