Email is the main channel. Public bug reports + feature requests go in the GitHub repo. There's no live chat or 24×7 phone — being a small team, we keep replies tight rather than diluted.
Email them to the address above — they go straight to the engineers, and we triage daily. If something in the docs is wrong or an API behaves unexpectedly, a copy-pasted request + response is the fastest route to a fix.
