what i found in the net about Ansible

One of the first books I read about ansible was "Ansible:Up and Running", the author is Lorin Hochstein. I can recommend this book 100% !
I had a good chat with him on twitter, and I have asked him about some more book recommendations.
This is answer : "Check out the list of books in @chrisparnin’s DevOps course https://github.com/CSC-DevOps/Course#books" ;)
