If you find a bug in Symfem, please report it on the issue tracker.
If you want to suggest a new feature or an improvement of a current feature, you can submit this on the issue tracker.
If you want to directly submit code to Symfem, you can do this by forking the Symfem repo, then submitting a pull request. If you want to contribute, but are unsure where to start, have a look at the issues labelled "good first issue".
On opening a pull request, unit tests and flake8 style checks will run. You can click on these in the pull request to see where (if anywhere) there are errors in your code.
We expect all our contributors to follow the Contributor Covenant. Any unacceptable behaviour can be reported to Matthew (symfem@mscroggs.co.uk).
