Your First Open Source Contribution: A Beginner's Guide with GitHub

Welcome to our guide on making your first open source contribution! If you've been following our GitHub for Beginners series, you already know about Issues, Projects, Actions, security, Pages, and Markdown. Now we're diving into the world of open source software (OSS). By the end of this Q&A, you'll understand what open source is, how to find projects to work on, how to navigate a repository, and how to make your first contribution. Let's get started!

What is open source software?

Open source software (OSS) refers to programs whose source code is freely available for anyone to view, use, modify, and distribute. Unlike closed source software, OSS is built in a transparent manner—the entire codebase, along with communication between developers, is publicly accessible. This transparency fosters collaboration and innovation. For beginners in software development, exploring OSS is an excellent way to gain real-world experience. You can work on projects used by millions of people worldwide, learn from experienced developers, and build your portfolio. GitHub is the primary home for open source, hosting millions of repositories. Understanding OSS is the first step toward contributing effectively.

Why should beginners contribute to open source?

Contributing to open source offers several benefits for newcomers. First, it provides hands-on experience with large, impactful codebases—something you rarely get from tutorials or personal projects. Second, you receive feedback from experienced maintainers and the community, which accelerates your learning. Third, it helps you build a public portfolio that can impress future employers. Fourth, you become part of a global community where you can network and collaborate. Finally, contributing is a great confidence booster: solving a real issue in a popular project is immensely satisfying. Even small contributions, like fixing a typo in documentation or addressing a beginner-friendly bug, can make a meaningful difference. Start small, and you'll quickly see how your skills grow.

How can I find open source projects to work on?

Finding the right OSS project can feel daunting, but GitHub makes it easy with several approaches. Start by searching for projects in a programming language you know. One powerful method is using GitHub Copilot Chat: navigate to github.com, open the Copilot chat window, and select the Ask mode. Enter a prompt like, “Find open source projects written in TypeScript that accept new contributors, with the good first issue label and over 100 stars.” Copilot will generate a curated list of repositories. Alternatively, you can manually browse GitHub's Explore page or use the Topics section to filter by language and beginner-friendly tags. The key is to look for repositories that explicitly welcome new contributors through labels like good first issue or help wanted.

How do I use GitHub Copilot to search for beginner-friendly issues?

GitHub Copilot can streamline your search for beginner-friendly issues. First, click the Copilot icon in the GitHub interface to open the chat panel. In the bottom-left corner, set the combo box to Ask. Then, craft a prompt specifying your preferred language and criteria. For example: “List open source Python projects with the good first issue label and at least 50 stars.” Copilot will scan GitHub and return matching repositories. Once you have a list, you can click into any repository and navigate to the Issues tab. There, use the Labels dropdown to select good first issue—this filters all issues tagged as beginner-friendly. This label is a sign that the project maintainers are actively seeking new contributors and have curated starter tasks.

What does the “good first issue” label mean?

The good first issue label is a tag used by maintainers to mark bugs or enhancements that are ideal for newcomers. These issues are typically well-defined, have a clear scope, and require minimal context about the project. They might involve tasks like fixing a small bug, improving documentation, writing tests, or adding a simple feature. When you see this label on an issue, it means the community expects beginners can tackle it with a reasonable amount of effort. Always read the issue comments and any linked contributing guidelines before starting. If you get stuck, you can ask clarifying questions—most maintainers are happy to help. This label is your best entry point to making your first meaningful contribution.

How should I read an open source repository before contributing?

Before jumping into an issue, spend time understanding the repository. Start with the README file—it explains the project's purpose, setup instructions, and often how to contribute. Next, check the CONTRIBUTING.md file (or similar) for specific guidelines: this might include coding standards, pull request workflows, and communication etiquette. Review the Code of Conduct to understand behavioral expectations. Browse recent issues and pull requests to see how discussions happen. Look at the project's documentation folder for additional context. If the repository uses a folder structure, examine how code is organized. For the issue you choose, read all comments and any referenced files. Taking these steps ensures you work efficiently and respect the maintainers' time, increasing the chance your contribution will be accepted.
