[ericmjl]

Welcome to the pyjanitor issue tracker! Here’s a few things to help you get oriented on the issue tracker. At first, it may seem overwhelming with the number of issues, but hopefully, reading this issue will help you get oriented around the rest of the issue tracker.

tl;dr

1. Keep it professional and friendly.
2. If you’d like to take on an issue, add a comment along the lines of, “I would like to work on this!” Then, go ahead and submit a PR.
3. For questions that you might have, see if a search through the docs might answer it first.
