I got started (with minimal knowledge and a love for tinkering) by installing proxmox on an old computer (i3 with 8gb of ram) and then using Proxmox Helper scripts https://tteck.github.io/Proxmox/. I run home assistant in a vm within proxomox and have a docker instance running in a container in proxmox. It's all been fairly easy so far, although I'm not sure I'd call it a one- or two- click solution. I got started from the home assitant community, and I'm new to the self hosted community, so I may do things a little differently from others around here.

My guess is op (or whoever wrote the title) wanted "reddit" to come first to grab people's attention. Definitely poorly written though.
