There’s no such thing as too simple to document. If you spent time learning how to install it, you’ll need to relearn it if you want to make any changes in the future. If you don’t leave at least some notes as to why you make some decisions, you’ll have to redo your work.

It’s also good to make notes on every configuration setting. That forces you to understand why the settings are the way they are. If you have a -f in a docker config and you don’t have any understanding of why that’s there, you might not know if it’s a development flag for getting things set up, or if it’s a critical part of your environment.

It is especially important if any of those parts are exposed to the public Internet. You might have a config set to allow unauthenticated connections and not know it.

There is an API that you can call to sync Kobo e-readers with calibre.

It just depends on if this would work with your current thoughts on how your app works.

I would be interested in something that can sync with Calibre-Web

Kinda cool how the configs work, but it feels like you need to rely a little too much on having premade configs available for the things you want to do.
