Hacktoberfest returns! Contribute to open source projects and win free swag


The sixth annual Hacktoberfest celebration is underway, and we’re happy to be a part of the contest once again!

Hacktoberfest is a month-long event that encourages members of the open source community to contribute to the projects they love. 

This year, during October, the first 50,000 people who submit at least four pull requests to any public repository on GitHub will receive a free t-shirt from sponsors DigitalOcean and DEV. If it’s your first time contributing to Mattermost, you’ll also earn some swag from us.

Hacktoberfest has come a long way in a short period of time. 

In 2014, the inaugural Hacktoberfest attracted 676 contributors. During last year’s event, more than 106,000 community members made over 412,000 pull requests. Altogether, they contributed to upwards of 106,500 different open source projects. 

Hacktoberfest 2019 is shaping up to be even bigger.

In a blog post last year, Mattermost CTO Corey Hulen shared some tips on how to choose an open source project to contribute to. Either start on a product you use or a community you’re involved in or look for a project that uses technologies you’re interested in.

If you want to contribute to Mattermost to gain experience with Go, React Native, and Kubernetes, that’s great. Take a look at our open Hacktoberfest issues on GitHub and stop by our contributors’ community channel to get involved.

We look forward to seeing what you help build.

Happy hacking!
