There is full online documentation to help you learn about all the features and usage.
Use our issue tracker on GitHub to see if your problem is reported, fixed, or needs to be reported. Perhaps you have a clarifying example? Insight into a reported problem? Want to request a feature or improvement?
You can ask for help at firstname.lastname@example.org. We request that you first look around at the full online documentation, and perhaps answer your own question. Remember, there is only a small group of volunteers reading these.
We are an inclusive community, and we welcome your feedback. We work together to make the software better. Everything else is out of scope. Please report any abuse.
