## How to Support Open Source

1. **Star repositories** on GitHub - It's free and helps projects gain visibility
2. **Sponsor maintainers** directly through GitHub Sponsors, Open Collective, or project-specific donation pages
3. **Contribute** code, documentation, or bug reports
4. **Cite** projects in your publications
5. **Share** projects with colleagues
