If anyone has questions let me know (as one of the authors).

I just watched the free course on Udemy by the authors. The book goes much more in depth but the course is free if you want an overview before you take a deeper dive by reading the book.

Alistair here—Ben and I learned a ton writing this, and have put a number of talks on Slideshare; let us know if you have questions. We love to hear stories of how the book's approaches are being used in the wild, too.

This was an awesome book. Worthwhile addition to any collection.
