I managed to get the docker compose up and running and I can login. I first failed to get it running on my Raspberry Pi 4, and I also failed to point the DB to an existing MySql container. But when I eventually tried your vanilla setup, it worked at first try.

One other little issue I found is that I couldn't set the APPLICATION_SECRET with the normal user, and start the docker with sudo docker-compose up -d. But that's not a real issue.

But now I am trying to configure the app and setup some categories and accounts, but I can't find the conf directory. How can I map that volume to a local directory?

Also, how can I change the EUR sign into a $?
