I just had my first post for the Braintree blog released today, check it out – https://www.braintreepayments.com/blog/api-where-to-begin
The first job I took on after joining Braintree was to help solidify, expand and generally make more comprehensible, the API documentation. We have an awesome API at Braintree, but the learning curve can be a little steep, so I am starting off by working on a Quick Start and then some easy-to-follow tutorials. I’ll update here as they are released.
