it's a pleasure to be on this forum, I'd like to develop my personal cloud system using the Nextcloud plugin and in the future I'd like to add Plex and virtual machines.
I'm looking forward to share suggestions and interesting ideas!
I'm also in the process of finally getting around to setting up Nextcloud, so I thought I'd share the following link. It's the most up to date, thorough Nextcloud tutorial I've found so far and you might find it to be helpful.
If you want to do the setup manually, that's the best guide I've seen. If you don't want to do the work yourself, my completely unbiased opinion is that my script is pretty good too. I wouldn't recommend using the plugin at all.
