While OP can generate MD, HTML and PDFs we've since moved away from that as the default to an approach in favour of just rendering the outputs as HTML/JSX.
You're 100% right we should make it easy for anyone just checking out the project to see the generated results without running the examples. I will add a CLI example and commit the generated policies to the repo.
Thanks for pointing this out and sorry our docs aren't up to the standard they need to be.
