Hi! I'm happy to accept grammatical PRs to the book. You could also report issues via Slack or Github issue. I will not be accepting larger PRs to the book, to maintain a consistent voice.

Cool! I'm still reading, but when I'm done I'll open a PR for the few small issues I've seen.

Thanks for your work on jank! I hope the Alpha brings you lots of new users, useful bug reports, and some contributors. :)
