For what it's worth, this is also a bit of a draft. I'm basically writing a book in public. Feedback, including grammar, pointing out spelling and typos, or any clarifying questions, is all very welcome. I have added a section to the intro (for right now) to include acknowledgements. If you provide feedback, please let me know if you would not like to be included or if you'd like to be included in a specific way other than just your handle.
