Crate sunrise_kernel

Sunrise kernel

Writing an Operating System is easy. Explaining how to write one isn't.

• PoC||GTFO, 4:3.

A small kernel written in rust for shit and giggles. Also, hopefully the last project I'll do before graduating from 42 >_>'.

Currently doesn't do much, besides booting and printing Hello World on the screen. But hey, that's a start.
