The CDF’s Guide to Hacktoberfest

Hacktoberfest 2021 is fast approaching!

This year, the CDF and its projects are participating in Hacktoberfest 2021.

What is Hacktoberfest?

Hacktoberfest is a month-long celebration of open-source software. Every October, everyone is encouraged to support open-source by contributing a minimum of 4 pull requests to earn limited-edition SWAG or to plant a tree.

Everyone is invited to participate and contribute regardless of your background or experience. All you need to do is sign-up to participate on the Hacktoberfest website.


Each CDF project has unique contribution guidelines. Click on a project logo below to find out how to contribute.

Important: we expect everyone participating to contribute valuable pull requests. Open-source folks work hard to maintain great projects for their communities. The CDF is participating in Hacktoberfest to help the projects improve and to bring new contributors into the mix. We will identify any abuses, if they arise, and adjust the prize nominees accordingly.

At the end of Hacktoberfest, top contributors will receive CDF SWAG! The top 4 contributors of each of the 6 CDF projects (Jenkins, Jenkins X, Ortelius, Screwdriver, Shipwright, Spinnaker, and Tekton) will receive awesome gear from the CDF SWAG store.

Sign-up here to be eligible for SWAG and read-up on how the “top” contributors are determined.
