🚀 The Complete Beginner’s Guide to Open Source Contribution

From Zero to Your First Pull Request — and Beyond to GSoC

Open source is one of the best ways to grow as a developer. It improves your coding skills, teaches collaboration, builds your public portfolio, and opens doors to internships, jobs, and programs like Google Summer of Code (GSoC).

This README is a beginner-friendly, end-to-end guide that explains:

• What open source is
• How to start contributing
• How to choose beginner-friendly issues
• How to make your first Pull Request
• How to grow in open source
• A complete Google Summer of Code (GSoC) roadmap

🌍 What Is Open Source?

Open source software is software whose source code is publicly available. Anyone can:

• Read the code
• Use it
• Modify it
• Contribute improvements

Popular Open-Source Examples

• Linux
• React
• Kubernetes
• Django
• Cal.com

Most open-source projects are hosted on GitHub.

🎯 Why Should Beginners Contribute to Open Source?

• Learn real-world coding practices
• Improve Git & GitHub skills
• Collaborate with experienced developers
• Build a strong public GitHub profile
• Increase chances for internships, jobs, and GSoC

🔍 Step 1: Choose the Right Open-Source Project

Beginner-Friendly Platforms & Organizations

• GitHub Explore
• First Timers Only
• Good First Issue
• Up For Grabs
• Google Summer of Code Organizations

Popular Beginner-Friendly Projects

• Cal.com
• Appwrite
• Supabase
• FreeCodeCamp
• PostHog

🏷️ Step 2: GitHub Issue Labels Every Beginner Should Know

When visiting the Issues tab, filter using these labels:

Label	Meaning
good first issue	Ideal for beginners
beginner friendly	Easy, low-risk issues
help wanted	Maintainers want help
documentation	Docs-related issues
bug	Fixing broken behavior
easy	Simple implementation

🚫 Avoid issues labeled:

• critical
• high priority
• architecture
• breaking change

🍴 Step 3: Fork the Repository

Forking creates your own copy of the repository.

Steps:

1. Open the project repository on GitHub
2. Click the Fork button (top-right)
3. The repository is copied to your GitHub account

---

💻 Step 4: Clone the Repository Locally

Clone your forked repository:

git clone <your-forked-repo-url>
cd project-name

Step 5: Create a New Branch

Never work directly on main or master.

git checkout -b fix-issue-123

Branch Naming Tips

• fix-issue-123
• docs-update
• add-validation

Step 6: Understand the Issue Before Coding

Before writing code:

• Read the issue description carefully
• Check linked files, screenshots, or logs
• Read existing comments
• Ask questions politely if unclear

Step 7: Make the Fix

• Modify only required files
• Follow the project’s coding style
• Run tests if available
• Avoid unnecessary changes

Step 8: Commit and Push Your Changes

git add .

git commit -m "Fix: resolve login redirect issue"

git push origin fix-issue-123

Commit Message Guidelines

• Clear
• Short
• Descriptive

Step 9: Create a Pull Request (PR)

1. Go to your fork on GitHub

2. Click Compare & Pull Request

3. Describe:

   • What you changed
   • Why you changed it

4. Reference the issue:

   Fixes #123

Be patient and respectful during reviews. Maintainers may request changes.

Step 10: Sync Your Forked Repository

Keep your fork up to date:

git remote add upstream <original-repo-url>

git fetch upstream

git checkout main

git merge upstream/main

git push origin main

Growing in Open Source (After First PR)

• Take slightly harder issues
• Improve documentation
• Review Pull Requests
• Become a regular contributor

🎓 Google Summer of Code (GSoC) – Guide

What Is GSoC? (https://summerofcode.withgoogle.com/)

Google Summer of Code (GSoC) is a global, paid program where contributors work on open-source projects under mentors for 12+ weeks.

GSoC Eligibility

• 18+ years old
• Student or beginner contributor
• Familiar with Git & GitHub
• Prior open-source contributions

GSoC Preparation Roadmap

Phase 1: Learn & Contribute

• Choose 1–2 organizations (https://www.gsocorganizations.dev/)
• Fix small bugs

Phase 2: Community Bonding

• Join Slack / Discord
• Communicate with mentors
• Understand codebase deeply

Phase 3: Proposal Writing

• A strong proposal includes:
• Problem statement
• Why the problem matters
• Technical approach
• Timeline
• Your past contributions

GSoC Proposal Tips

• Be specific
• Include GitHub PR links
• Align with organization goals
• Follow organization templates
• Keep timelines realistic

❌ Common Beginner Mistakes

• Using AI to blindly generate code and opening PRs without understanding the code
• Submitting spam PRs just to increase contribution count
• Copy-pasting solutions without testing or reading project guidelines
• Ignoring maintainer feedback or review comments

✅ Best Practices Instead

• Make small, focused PRs that solve one problem
• Understand every line of code you submit
• Use AI only as a learning or assistance tool
• Communicate clearly with maintainers
• Prioritize quality over quantity
