### The goal
Writing a hobby operating system to better understand the basic building blocks of any operating system.Initially I'd like for my 
operating system to be able to run bash.

### Operating System Technical specs/details
The operating system can print strings to the 
screen. The terminal/screen has scrolling so the latest messages are visible on the screen.
