-**Caution**: This repository is a remake of my old course. It was written several years ago [as one of my first projects when I was in High School](https://github.com/SamyPesse/devos), I'm still refactoring some parts. The original course was in French and I'm not an English native. I'm going to continue and improve this course in my free-time.

 ### What kind of OS are we building?
 
-The goal is to build a very simple UNIX-based operating system in C++, not just a "proof-of-concept". The OS should be able to boot, start a userland shell, and be extensible.
