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.
