This folder's configuration is deployed over at op.panva.cz. Every time a commit lands on master it is re-deployed and tested using OIDC Conformance test suite. It features a couple of shortcuts (read hacks), that make it possible to re-use the regular example codebase and to make sure that the dynamic clients you may register on this instance are short-lived. Hop over to the regular example folder or step by step repo for inspiration, not here ;)
If you can follow the code tho, by all means, try it. Just copy pasting this though, I wouldn't recommend it without understanding it first.
