# Hobby Operating System

This is a modern 64-bit UEFI based UNIX-like hobby operating system. It has been an 

ongoing project for a while and I treat it like a sandbox to learn about operating

system design and other low-level concepts. It is not yet fully working (no userspace 

or shell), but I have been slowly working towards the goal of running doom in userspace.

Currently, it has a working bootloader, memory management, scheduler, usb support (hid, 

mass storage),  and a few other things. I read a lot of source code from other projects

while working on this so maybe this could be useful to someone else.
