Celebrate open source this October by participating in Hacktoberfest, a month long festival of code organized by DigitalOcean and hosted on GitHub.
How to participate
Participation is simple: Choose any open source project hosted on GitHub and contribute by sending a pull request. You can fix a bug, add a feature, or even improve some documentation. Once you’ve made your contribution, tell the world about it by sharing with the #hacktoberfest hashtag so we can celebrate with you.
Starting tomorrow, and each day throughout the month of October, there will be an interesting open source project that is looking for contributors highlighted on the Hacktoberfest website. If you need help getting started, be sure to check out our guide to contributing to open source.
