Hey! Thank you for your kind message, I always love seeing how people use YAMS on their servers :)

Regarding adding SABNzbd, you can add it yourself by using the custom docker-compose file that comes with YAMS! You can see how that's done here: https://yams.media/advanced/add-your-own-containers/

I was thinking about making some stickers... Maybe that can be done later? 🤣

This is actually one of my use cases! So it definitely works.

I configured YAMS as usual and then used TRaSH Guides to configure it for Anime, you can check it out here: https://trash-guides.info/Sonarr/

YAMS needs a 64bit OS to run. Are your running Raspbian 64 bits?
