systemd-less installation?

[romanrm]

Hello,

The page at https://rustdesk.com/docs/en/self-host/rustdesk-server-oss/install/ wants me to use docker or install.sh, and the latter also requires systemd.
I do not use docker or systemd.
Could you please add a brief install howto without install.sh?
Which keys I need to generate and put them where. What else is needed.
Then we can launch hbbr and hbbs via our own ways and our own service managers.
As is, trying to gather install instructions from reading the shell script, is an absolutely "amazing" user experience.

Thanks
