@boris Thanks for sharing piefed, enjoying looking into it.
@rimu has made a really nice effort with a video to new devs into the project's intentionally simple #python / #flask / #bootstrap codebase here: https://join.piefed.social/2024/01/22/an-introduction-to-the-piefed-codebase/
I would (and will) definitely recommend this as a watch to developers on their learning track, as a comprehensible look into a living codebase.
