10 Pro Tips for Open Source Success
Discover the insider secrets that make your contributions stand out and help you succeed in open-source development.
1. Start Small, Think Big
Your first contribution should fix a typo, improve a comment, or add a small feature. Don't try to refactor the entire codebase on day one. Small wins build momentum and help you understand the codebase incrementally.
Action: Look for issues labeled "good first issue," "help wanted," or "documentation." Not sure where to search? See our step-by-step guide to finding good first issues.
2. Read the CONTRIBUTING.md File
Before you even look at code, open CONTRIBUTING.md. This file tells you:
- How to set up the development environment
- Code style requirements
- How to run tests
- How to submit a Pull Request
Respecting the contribution guide shows you're serious and makes the maintainer's job easier.
3. Communicate Before You Code
Don't spend 3 hours coding a solution only to have the maintainer say "We don't want that feature." Instead:
- Comment on the issue and ask for clarification
- Propose your approach in a comment
- Wait for approval before diving in
A simple comment like "Hi! I'd like to work on this. My approach would be to [describe]. Does that sound good?" saves hours of wasted effort.
Pro Tip: Some maintainers assign issues to contributors. Asking first prevents duplicate work—someone else might already be on it.
4. Write Clear, Focused Pull Requests
When you submit a PR, the description matters as much as the code:
- Reference the issue it fixes: "Fixes #123"
- Explain what changed and why
- List how to test the changes
- Mention if you added tests
A maintainer reading your PR should understand your changes in under 2 minutes. For a deeper look at what a maintainer is actually thinking when they open your PR, we have a dedicated guide.
5. Follow the Code Style
Every project has conventions:
- JavaScript: spaces vs. tabs, quotes, semicolons
- Python: 4 spaces indentation, PEP 8 style
- Rust: formatting via
rustfmt
Run linters and formatters before submitting. Most projects have CI that will fail your PR if the style is wrong. Fix it before submitting, not after.
6. Write Tests for Your Changes
This single tip will make your PR stand out immediately. Most new contributors don't write tests. Those who do get merged faster.
- Add unit tests for your code
- Test both happy and unhappy paths
- Make sure existing tests still pass
You don't need 100% coverage, but a test or two shows you care about quality.
7. Respond to Feedback Gracefully
Maintainers will ask for changes. This is normal—it doesn't mean you failed. When they ask for revisions:
- Don't get defensive
- Ask questions if you don't understand
- Make the changes promptly
- Thank them for the feedback
This is how you build a reputation as a professional collaborator.
8. Update Your Local Fork Before PR
Before submitting a PR, sync your fork with the upstream main branch:
git fetch upstream
git rebase upstream/main
This prevents merge conflicts and shows your PR is based on the latest code.
9. Document Your Code
Add comments to complex logic. Docstrings for functions. If someone who's never seen your code needs to understand it, will they?
- Write clear variable names (not just
x) - Explain the "why," not the "what"
- Add docstrings/JSDoc comments to public functions
10. Be Patient and Appreciative
Open-source maintainers are volunteers. They might take days or weeks to review your PR. That's okay. When they finally merge:
- Say thank you
- Ask if there's more you can help with
- Share your contribution (it's a real accomplishment!)
Building relationships with maintainers opens doors to mentorship and more opportunities.
Bonus: Common Mistakes to Avoid
❌ Don't
- Submit massive PRs that refactor multiple systems
- Skip the CONTRIBUTING.md file
- Change unrelated code in your PR
- Ignore linter/CI failures
- Be rude or impatient with maintainers
- Submit code with zero tests
✅ Do
- Start with tiny PRs to learn the process
- Read contribution guidelines
- Keep PRs focused and small
- Fix CI failures before asking for review
- Be respectful and patient
- Write at least one test
