Under-used settings: `APP_DIR`, `STATIC_DIR`, `TEMPLATE_DIR`

Nice little guide. Just a note for the ones reading: the config file is already defining the path for the app folder, the static folder or the templates folder.

So when you are reading Chapter 1, don't forget that you could use the Pydantic Settings class directly instead of giving strings as paths.

Thanks for the comment. I'll take a look soon and make the adjustment!
