Thanks for your interest in contributing! The help is welcome. Hopefully these guidelines help you help....
The guidelines for issues are as follows: don't be shy. As much detail as possible is always welcome, but issue volume around here is pretty low, so it's not a real burden to address stuff even if it's accidentally a dupe or needs some follow-up questions.
- To submit a change, just follow the standard fork/code/pull-request Github workflow
- Feel free to submit pulls marked "WIP" (Work in progress) to get early feedback and help
