Inspired by people like Linus Torvalds and Andreas Kling

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.
