There are a number of minor issues with this doc https://github.com/aerogear/mobile-core/blob/master/docs/walkthroughs/developing-apbs-locally.adoc

The document heavily emphasises pushing images to a self owned org in the dockerhub as part of a dev workflow. I believe this is no longer the best flow. Since we use a newer version of the Ansible Service Broker, it's possible and much easier/faster to push images to the local openshift registry. This is currently documented but near the end of the doc and it almost looks like an afterthought. I think the doc should recommend this approach first.

In addition there are some minor steps missing such as adding the appropriate roles to the developer user to allow pushing and listing of apbs.
