LOL well I suppose you could. But no, we just dropped the Retro Pie image right on the SD card using an imaging tool.
There were several guides going over it, and honestly after reading a lot of them, I was expecting to spend more time teaching the kids about everything, but honestly it just worked out of the box, even the USB game controllers.
Tweaked it a bit after, but that was about it.

Sometime this winter, I'm going to build a homebrew keezer/kegerator. Raspberry Pints is the next project on the list.
