Welcome to the Hux kernel wiki!

Developing A Toy OS Kernel From Scratch

I will document the whole development process of Hux plus everything I reckon important here. This wiki essentially serves as a tutorial on how to develop one's own toy OS kernel from scratch. I will try to keep a balance between theory and practice (implementation), and explain all the important details in a clear way.

If there are any typos/mistakes/errors, please raise an issue!
