Single-user docs

[appsforartists]

I'm on immutable SteamOS and curious about system-manager. (Arrived here from @soupglasses/nix-system-graphics.)

It's unclear if I should expect this to work. The only mention of single-user mode is a tip in the README that says look in Getting Started. I don't see a document of that name, and I don't see anything about single user mode in the manual.

Please update the README to link to information about using single-user mode (or include that directly in the README).

Hi! We’re in the process of updating the documentation, and we address this point in it. The new documentation should be available later this week. But not to keep you waiting — presently System Manager only runs when Nix is installed for “all users.” Hope this helps; if not, let us know. We’re here to help.
