Hey OroPla, thanks for your comment. I agree I have work to do in terms of making the site more approachable to new users. I'd really value any ideas you have to that end.

Yesterdays is fully open-source, and while the production site runs in Kubernetes, the development setup in Docker Compose might meet your needs. If you ever wanted to talk through the process of running Yesterdays for your dad's collection, I'd be glad to help you with that.

Cheers!
