To my knowledge, this is the first online documentation that exposes the secrets of RPM-OSTree in a practical manner, with code examples at every step of the way. While it started as a set of Wiki pages on this topic, it ended up in some sort of a mini online book, taking the reader from theoretical concepts to practical samples, from simple to complex, in a progressive way. I've tried as much as I can not to duplicate information that is already available at the [OSTree official site](https://wiki.gnome.org/Projects/OSTree), limiting to only how much is needed to understand the practical examples. I wrote this mini-book from my own notes, based on my own experiments with this technology and working with my counter-part developer for the feature. It was necessary to understand how RPM-OSTree works in order to prepare test cases for its Photon application, even though public documentation is very sparse and sample code was almost non-existent. We've set the ambitious goal to make it work in Photon OS Technology Preview 2, which has been unveiled at VMWorld 2015 in San Francisco, along with a suite of other products in the same family. Many thanks to Touseef Liaqat, the main developer who wrote the Photon / RPM-OSTree integration code. Also, many thanks to the people (whom I never met) who designed this cool technology. Except for some school project and my short stint at Amazon, I have not developed much in Linux. I've worked for Microsoft for over 13 years, where in the old days just pronouncing "Linux" or "open source" was sure to [make some people uncomfortable](http://www.theregister.co.uk/2001/06/02/ballmer_linux_is_a_cancer/). Now things have changed even over there. I just turned two months ... of employment with VMware and I'm part of a team that puts together a Linux distribution built from scratch. It's been awesome so far!
