Thank you for wanting to contribute, we really appreciate it. Please look at our Code of Conduct before getting started.
For the time being we will only respond to bugs and reports of security vulnerabilities, so please don't raise PRs. In the future we will be looking for code contributions, so watch this space.
Please create a github issue describing the bug and including as much detail as possible. Check first that someone hasn't raised a similar issue already.
Please see the "Security" section in the README file.
