Just like this:

This installation tool will set up your computer with the Nix package
|

manager. This will happen in a few stages:
|
||||
|
||||
1. Make sure your computer doesn't already have Nix. If it does, I
|

will show you instructions on how to clean up your old one.
|
||||
|
||||
2. Show you what we are going to install and where. Then we will ask
|
||||
if you are ready to continue.
|
||||
|
||||
3. Create the system users and groups that the Nix daemon uses to run
|
||||
builds.
|
||||
|
||||
4. Perform the basic installation of the Nix files daemon.
|
||||
|
||||
5. Configure your shell to import special Nix Profile files, so you
|
||||
can use Nix.
|
||||
|
||||
6. Start the Nix daemon.
