Here is a picture of a cat

I spent a LOT of time yesterday and today going through documentation and old code from my other website projects to figure this out.

It didn't take that much time compared to the last attempts, but that's mostly because I had my old code to work with. I copied a lot of that old code verbatim. The thing that tripped me up the most was the caddy configuration because I had no backup of that.
