Hey.
The coinbox core will not get you anywhere alone. You will have to get at least the "base" module to get a UI, and add the other modules you need.
I'd recommend cloning them all, and have a look at the code. Set the output to debug. Disable some modules, see what each one does. Check the code if you want. Then only fork the ones you want to change things on. (I'll respond to your other message and tell you the best way to do that. I'll pin that as the first post)
The wiki on github was not setup since we were expecting to have the necessary instructions on the website, which was online, and then went offline, and will be online again...
