Hello! I’d like to contribute to this project, but I don’t want to duplicate anything that you’re actively working on. Is there anything on this issue that I can pick...

There is [official documentation](https://nixos.org/manual/nix/stable/installation/installing-binary.html#uninstalling) on the Nix website now. If I have time later today, I'll try to get a PR in - seems fairly straightforward.
