Continuous Delivery Applied: Idea to Code to Customer in < 1 Hour
About the Book
Apologies, but it's looking very unlikely this book will be finished. You can still read it if you want, and the book is now free. Leanpub allows you to voluntarily pay for the book, and if for some reason you choose to do this then 100% of the proceeds will go to the nominated charity listed at the bottom of the page.
