Just fork it/download and run ! It is main goal of this project, SIMPLIFICATION !
Sample use cases for calling external services established, sample acceptance and unit tests written, if you do not have idea how to do it on your own, just copy existing examples.
Hystrix gives us security - use cases for things like circuit breaker or collapsing are documented(using tests !)
Basic stuff needed to communicate with other services is prepared, just send JSON and receive JSON, no worries about dependencies in maven or mapper for javax.
