MOTO backend service how to create bucket

By any chance anyone can point me to correct direction? I'm trying to run the moto (https://github.com/spulec/moto) as backend service so that i can test out my application. I am able to run the moto service and load the webpage of the moto-api as suggested (http://localhost:5000/moto-api/#).

I have the question, how do i setup all my test bucket and instances for this backend service?

Thanks.
