in my opinion this is not realy correct.
Zoneminder normal works with Apache as webserver.
So need to do a lot of work by hand.
Easiest way is to use docker instead.
What is incorrect? I don't think zoneminder needs it own plugin. Whether you use docker or install it manually, I don't care but that doesn't change the fact there would nothing in the web interface except for an enable button. I agree Docker is probably the easiest but I never commented on ease of installation.
