🚀 Why Contribute to Open Source?

  • Build Real Experience: Work on production-level projects and learn best practices.
  • Collaborate Globally: Connect with developers, maintainers, and organizations around the world.
  • Boost Your Resume: Open source contributions are visible, verifiable, and valued by employers.
  • Give Back: Support the software ecosystem that you benefit from daily.

🧠 Part 1 — Setting Up Everything

1. Create Your GitHub Account

  • Sign up on GitHub.com.
  • Set a professional username and add your real photo.
  • Enable 2FA (Two-Factor Authentication) for account safety.
  • Write a short bio and link your LinkedIn, portfolio, or website.

2. Install Git and Configure It 

git config --global user.name "Your Name"
git config --global user.email "youremail@example.com"
Enter fullscreen mode Exit fullscreen mode

This ensures every commit you make shows your identity properly.

3. Essential Tools

  • VS Code – For coding and version control integration.
  • GitHub CLI – To interact with GitHub directly from your terminal.
  • GitHub Desktop – If you prefer a graphical interface over the command line.
  • GitHub Codespaces – Cloud-based development environment, no local setup needed.

🧭 Part 2 — Understanding the Workflow

Every open source contribution follows a similar pattern. Once you understand this, contributing becomes second nature.

  1. Fork: Copy the main repository to your own GitHub account.
  2. Clone: Download it to your local machine. 
git clone https://github.com/your-username/project-name.git
Enter fullscreen mode Exit fullscreen mode
  1. Branch: Create a new branch for your changes. 
git checkout -b feature/add-login-page
Enter fullscreen mode Exit fullscreen mode
  1. Commit: Save your changes with a clear message. 
git add .
git commit -m "Added login page feature"
Enter fullscreen mode Exit fullscreen mode
  1. Push: Upload your branch to your GitHub fork. 
git push origin feature/add-login-page
Enter fullscreen mode Exit fullscreen mode
  1. Pull Request: Open a PR from your fork to the main repository.
