Alright! We're done!

Before Nix will work in your existing shells, you'll need to either
run:

  $ source /nix/var/nix/profiles/default/etc/profile.d/nix-daemon.sh

or close them and open them again. Other than that, you should be
ready to go.

Try it! Open a new terminal, and type:

  $ nix-shell -p figlet -p lolcat --run "echo 'nix rules' | figlet | lolcat"

Thank you for using this installer. If you have any feedback, don't
hesitate:

We'd love to help if you need it.
