For New Contributors

If you are interested in contributing to Pulp, the best way is to select a bug that interests you and submit a patch for it. We use Redmine for tracking bugs. Of course, you may have your own idea for a feature or bugfix as well! You may want to send an email to or ask in the #pulp-dev channel on freenode before working on your feature or bugfix. The other contributors will be able to give you pointers and advice on how to proceed. Additionally, if you are looking for a bug that is suitable for a first-time contributor, feel free to ask.

Pulp is written in Python. While you do not need to be a Python expert to contribute, it would be advantageous to run through the Python tutorial if you are new to Python or programming in general. Contributing to an open source project like Pulp is a great way to become proficient in a programming language since you will get helpful feedback on your code.

Some knowledge of git and GitHub is useful as well. Documentation on both is available on the GitHub help page.
