What can I do?

Our issue tracker contains lots of issues you could work on. If you are new to Jenkins, you could start by fixing some easier issues. In the issue tracker we mark such issues with the newbie-friendly label (search query). You can also submit your own issue and propose a fix.

How do I label issues and pull requests?

Hacktoberfest project requires issues and/or pull requests to be labeled with the hacktoberfest label. You may have no permissions to set labels on your own, but do not worry! Just mention @jenkinsci/hacktoberfest or @jenkins-infra/hacktoberfest in the repository, and we will set the labels for you.

How do I get reviews?

All examples above are being monitored by the Jenkins contributors, and you will likely get a review within few days. Reviews in other repositories and plugins may take longer. In the case of delays, ping @jenkinsci/code-reviewers in your pull request or send a message to the mailing list.
