The README opens with
Grab an API key from the TypeSafe console and hand it to the client. It uses jev-latest unless you tell it otherwise.
There are three question types. Every question takes optional instructions, and instructions and criteria can be a string, a hash, or an array if you need more structure than a sentence. See primitives for when to reach for which.
Noul is a yes/no question. The answer is the probability of yes, from 0 to 1. Criteria are optional.
