`nix-env -iA nixos.emacs`

But I do agree with you, it's not as straight-forward as it should be yet. But I absolutely love how I can be certain that no garbage is accumulating on my computer like I needed this program one time and I don't even know what does it do, yet I have it's complete dependency graph installed that the package manager can barely uninstall. In nix I just create a `nix-shell -p package` for one time use, do my work and then forget about it. At the next `nix-collect-garbage` it will be removed from my computer completely.
