The first step is to find an existing open source project that interests you and that you think you could potentially contribute value to. Some good places to search for open source projects include GitHub, SourceForge, GitLab, and similar platforms where many open source developers host and manage their code. You’ll want to browse through projects in areas that align with your skills and interests. Consider factors like the project’s activity level, number of open issues, how beginner-friendly it seems, and whether the codebase looks accessible enough for you to potentially make meaningful contributions as a new contributor.

Once you’ve identified a few potential projects, review their documentation to understand what types of contributions they are looking for and any guidelines they have for new contributors. Pay close attention to contribution guidelines and style guides, as following these properly will be important for having your code merged. You may also want to look at the project’s issue tracker to get a sense of common issues and potential ones you could help resolve. At this point, it’s a good idea to join the project’s communication channels like Slack or Discord if they have them to start to engage with core developers.

With a potential project in mind, the next step is to pick an issue or feature that interests you and seems achievable within the scope of a capstone. Review the issue description and any conversations thoroughly to fully understand what is being requested. You may need to ask clarifying questions in the issue. For enhancements or new features without an existing issue, you’ll need to provide a clear proposal in a new issue before beginning code work. Get explicit agreement that your proposed contribution would be a good fit for the project.

With an agreed upon task, you are ready to start coding! Be sure to fork the project’s repository to your own GitHub or other hosting account before making any code changes. As you work, document your process through comments in the code and updates in the applicable issue. Write thorough tests to validate your code works as intended. Check any style guides and follow the project’s code formatting and quality standards. Commit changes to your fork frequently with detailed, self-explanatory commit messages.

Once you have completed your task and tested your changes, you are ready to submit a pull request for review. A high-quality pull request is important, so take time to write a description clearly explaining your changes and how to test them. Request reviews from one or more core committers listed on the project. Be sure to address all feedback in the pull request conversations, even making additional commits if needed. Having an effective review process is important to learn from before the code is merged.

With all feedback addressed, the pull request is ready for final merging once all reviewers have approved. Celebrate your first open source contribution! Consider additional issues you could take on, or ways to otherwise continue engaging with and supporting the community. You’ll want to document your experience contributing to the open source project as part of your capstone paper or report. Highlight what you learned, challenges you overcame, and how contributing aligns with your academic and career interests and goals going forward.

Maintaining a good relationship with the open source project you contributed to can be valuable for references or future collaboration opportunities. Continue engaging on communication channels, consider taking on more significant issues, or potentially helping with overall project management tasks if your contributions are appreciated. Promoting your work on social media is also an excellent way to demonstrate your skills and experience to potential employers.

Contributing to an open source project can be a highly rewarding learning experience when done right. Taking the time to thoughtfully select a project, clearly define the scope of your work, communicate effectively, and thoroughly test your code will serve you well throughout your software development career. It’s a process that takes patience but pays off in learning valuable new skills that can also be highlighted on your resume or capstone. With practice, contributing to open source can become very natural ways to both learn and give back to the community.
