Hey Oscar

Thanks for your interest. This was a temporary repo to share with someone. It will need rework... including the README.

Interested in helping me and the MCM chapter? Ping me on slack. Thanks

Sure,

So the CRD for the cluster I was working on didn't have the GitHub enum type, this resolved this issue:
