Installation on Synology NAS without Docker-Support

Hello, I have a Synology DS220j NAS which does not support Docker. It has an ARMv8 64-bit processor and I would like to store my passwords on this device. Where do I start when I want to get Vaultwarden to work without Docker?

I also opened a Discussion on GitHub Vaultwarden without Docker on Synology NAS · Discussion #2735 · dani-garcia/vaultwarden · GitHub
