Ask HN: Where to learn about HIPAA compliance?

Software developer here. I have been working on HIPAA-compliant software for a while for a small company. I have a good grasp on the technical side (encryption, audit trails, access control, etc) but I can't find any resources to help me understand the "processes" required by HIPAA.

I have bought a highly-rated book on understanding HIPAA, but have been disappointed in how vaguely it covers the topic.

How does a developer learn and understand concrete HIPAA compliance without working in an already-compliant organization? Can anyone recommend online courses (paid or free) that break it down from square 1?

It'd be nice to have this knowledge for my resume, but I don't know where to even begin learning.
