Overview
Open source software (OSS) is everywhere—from operating systems to web frameworks—and contributing to it is a fantastic way to gain real-world experience, build your portfolio, and join a global community of developers. If you’re new to programming or GitHub, the thought of making your first contribution can feel overwhelming. This guide will walk you through exactly what open source is, how to discover beginner-friendly projects, how to read a repository like a pro, and finally how to make your first contribution. By the end, you’ll have the confidence to take that first step into the open source world.
This tutorial assumes you have a basic GitHub account and some familiarity with Git commands (or a Git GUI). We’ll focus on GitHub’s features that make contributing easier, including GitHub Copilot Chat, issue labels, and the ever-important CONTRIBUTING.md file.
Prerequisites
What You’ll Need
- A GitHub account (if you don’t have one, sign up at github.com)
- Basic knowledge of Git (cloning, branching, committing, pushing) – we’ll recap the essentials
- Familiarity with at least one programming language (e.g., Python, JavaScript, TypeScript)
- Git installed on your local machine
- A text editor or IDE (like VS Code)
No prior open source experience is needed – that’s what we’re here to build!
Step-by-Step Instructions
Step 1: Understand Open Source Software
Open source software means the source code is publicly available for anyone to view, use, modify, and distribute. Unlike closed-source (proprietary) software, OSS encourages collaboration and transparency. GitHub is the largest host of open source projects, providing tools like issues, pull requests, and discussions to facilitate contributions.
Contributing isn’t limited to code – you can also help with documentation, design, testing, or community support. For beginners, fixing a typo in documentation or solving a “good first issue” is a perfect start.
Step 2: Find Beginner-Friendly Projects
The hardest part is often finding a project that welcomes newcomers. Here are two effective methods:
Method A: Use GitHub Copilot Chat
- Navigate to github.com.
- Click the Copilot icon (usually in the bottom-right corner) to open the chat panel.
- In the chat window, select the Ask mode from the dropdown.
- Enter a prompt like:
"I’m looking for a list of open source projects written in TypeScript that are accepting new contributors. Search GitHub and narrow down the list to repositories that use the 'good first issue' label and have over 100 stars." - Copilot will return a curated list of repositories with beginner-friendly issues.
Adjust the language and criteria (e.g., stars, topics) to match your interests.
Method B: Manually Search Using Labels
- Go to any popular repository, e.g., microsoft/vscode.
- Click on the Issues tab.
- Click the Labels dropdown and type good first issue.
- Select that label; the page will now only show issues marked as beginner-friendly.
This label is used by thousands of repositories to highlight tasks that are well-scoped and ideal for new contributors.
Step 3: Read the Repository Like a Pro
Before jumping into an issue, you must understand the project’s structure and expectations.
Check the README
The README.md explains what the project does, how to install it, and how to contribute. Look for a section titled “Contributing” or “How to Contribute.”
Read the CONTRIBUTING.md
If present, this file contains specific guidelines: coding standards, commit message format, pull request process, and how to set up a local development environment. Always follow this file – it’s your roadmap.
Understand the Code of Conduct
Most projects have a CODE_OF_CONDUCT.md that sets expectations for respectful collaboration. Read and abide by it.
Look at Recent Issues and Pull Requests
See how maintainers interact with contributors. This gives you a feel for the project’s communication style.
Step 4: Make Your First Contribution
Once you’ve found a good first issue and read the guidelines, it’s time to contribute. The typical workflow is:
- Fork the repository (click the “Fork” button in the top-right of the repo).
- Clone your fork locally:
git clone https://github.com/YOUR-USERNAME/REPO.git - Create a new branch for your changes:
git checkout -b fix-typo-in-readme - Make your changes – edit files, test them locally if possible.
- Commit your changes with a clear message:
git commit -m "Fix typo in README" - Push your branch to your fork:
git push origin fix-typo-in-readme - Open a pull request (PR) from your fork to the original repository. Use the GitHub interface to describe what your PR does.
After submitting, be patient: maintainers may request changes. Respond promptly and politely.
Common Mistakes
1. Not Reading the Contributing Guidelines
The biggest mistake is ignoring CONTRIBUTING.md. Each project has its own conventions – skipping this can lead to rejected PRs.
2. Making a Massive Pull Request
New contributors often try to fix everything at once. Instead, make small, focused changes that address a single issue. It’s easier to review and more likely to be accepted.
3. Forgetting to Communicate
If you’re unsure about an issue, ask questions in the issue thread. Also, if you start working on an issue, comment to let others know you’ve claimed it (or assign yourself). Avoid silent work – collaboration is key.
4. Ignoring the Code of Conduct
Open source communities value respect. Avoid rude or entitled language. If you’re frustrated, take a break before replying.
5. Submitting Unrelated Changes
Keep your PR focused on the original issue. Don’t sneak in formatting fixes or other unrelated edits – they cause merge conflicts and slow things down.
Summary
Contributing to open source is a rewarding journey that starts with finding the right project. Use GitHub Copilot Chat or issue labels like good first issue to discover beginner-friendly tasks. Always read the project’s README, CONTRIBUTING.md, and code of conduct before starting. Then fork, branch, commit, and submit a pull request – following the project’s guidelines. Avoid common pitfalls like overcommitting or ignoring communication. With practice, you’ll become a confident open source contributor.
Now go ahead and make your first contribution – the open source community is waiting for you!
