I'm familiar with docker in general but still newer to the ARR stack and the idea of self hosting media on a server in my home. The things I know I want

Jellyfin
Jellyseerr
Radarr
Sonarr
Prowlarr
qBittorent, and I know qBittorent runs behind a vpn via gluetun etc.

My issue comes in here - I know there's a ton of stuff in this stack I don't necessarily care about or want. Like if I'm using Jellyfin I can remove Plex from docker compose, this is an obvious one. However, there's a lot of stuff in there that isn't obvious what exactly it's being used for (like guacamole or portainer etc)

So having a dependency tree would be nice so that a newcomer can make better and easier decisions on what they can safely remove from the stack you have provided without affecting functionality of core components.
