Hey! Keith here, "project" lead and such. Welcome to the readme!

To run names.py script, err, install python. It should be pretty lean on specific dependencies (hell, I'm only importing "random").
To run names.html, use a web browser?
To run arpg.html, you'll need Bootstrap, and you'll have to re-write the paths (I've hard-coded them for my own website at the moment; I may rethink that later).
