"""One of the best Continuous Delivery books of all time"" - BookAuthority (https: //bookauthority.org/books/best-continuous-delivery-books?t=5zr5rp&s=award&book=1790256348) The content is helpful in understanding the concepts but it is poorly written. Lots of typos and poor grammar. Needed a better editor. Laura (Amazon Customer) i'm glad to purchase this Continuous Delivery book. I would recommend for everyone that wants to learn Site Reliability Engineering. This book explained the basics and Very Nice detailed processes Non-Programmer's Guide. this one was a great introduction. Happy Heart (Amazon Customer)"
