Is your feature request related to a problem? Please describe.

Describe the solution you'd like
It should go along something like this.

• Forget everything you know about an operating system
• When you boot up you OS you see the following

• A script is a series of commands that get run in sequence
• To get to the O.S. That you know, enter a standard boot command to run a series of scripts
