This issue serves as a place to allow anyone from the community to provide feedback that we can then take into account while we work on the second edition of the book. Feedback can just be a comment here, or even a PR on top. But do start with a comment here first so we can make sure to be aligned.

If there is content missing, not well formulated or that should be removed. Let me know.
