To get BitBot off the ground, there's some API-keys and the like in bot.json.example. move it to bot.json, fill in the API keys you want (and remove the modules that rely on those configs.)
On first boot, he'll ask for a first server to connect to then exit. do `./start.py` again and he'll connect to that server and join #bitbot (to get him to join other channels, simply invite him to them.)
