Based on feedback that Atomic Registry was overly complex to configure and maintain, I have provided a simplified systemd-based deployment method[1].
Install/config docs[2] will be updated ASAP to reflect this. Until then the source README should be sufficient to get you going. Feedback encouraged! Reply to this thread or IRC #atomic. Thank you. -Aaron [1] README: https://github.com/openshift/origin/tree/master/examples/atomic-registry/systemd [2] docs: http://docs.projectatomic.io/registry/
