 ## Credits/Resources
 A sizable percentage of this code was borrowed and adapted from [Stefan Scherer](https://twitter.com/stefscherer)'s [packer-windows](https://github.com/StefanScherer/packer-windows) and [adfs2](https://github.com/StefanScherer/adfs2) Github repos. A huge thanks to him for building the foundation that allowed me to design this lab environment.
