Help with *arr softwares

I don't know what TrueNAS is but I have Sonarr, Radarr, Prowlarr, Bazarr installed on my DietPi on RaspberryPi. Let me know if I can help.
 
Well this is what I did:
Installed jellyfin - metadata crawling didnt work.
Installed plex - metadata crawling did work. - tangent, not relevant
Installed jellyseer - assumed that it will allow me to request media from other users
Jelly seer asked me to configure sonarr & radarr.
And here I am. ??????

I know of the arr stack but I am looking for a guide for me to install them all with minimum fuss. I am already wrestling with jellyfin's crawling failure.
Any suggestions?
 
Sonarr, and radarr adds movies, and tv show to you library.

You need to configure jackett/prowlarr for Sonarr, and radarr to find torrents(torrentleech/galaxy etc). For a couple of the torrent websites you might need a VPN to access those reliably.

You would also need a torrent client for them to download torrents. Or configure Usenet.

Jellyfin/Plex will find the media downloaded, and you can use the clients of these to watch media wherever you want.

After configuring Sonarr/radarr you can use jellyseerr/overseerr to add media to them easily.

I use them on docker but I think you can use docker/containers in truenas too.
