nit: can you please use lowercase in the file name?

I'm failing to understand the rationale here? Why would someone do that in production? Nobody is going to use nohup or multiple terminals. Production will use container images (via systemd unit) or run the distro server with a systemd unit.

If the argument is around developers, I don't think this needs to be documented either. We have a getting started guide that offers multiple options, too. If people are looking at running multiple instances for whatever reason, they should be able to figure that out without needing explicit instructions from us.

@leseb I understand your point, would it be helpful to create documentation for spinning up multiple LS servers for production container deployments?

Yes I see value in that. Not necessarily multiple instances but at least containers running through a systemd unit. Thanks!
