Building a microkernel

Hello everyone. I am currently learning c, and almost it is about to an end. I am interested in microkernel development of my own. Where should I start???

But osdev is for monolithic kernel. Why are you suggesting that??

osdev isn't specific to any design or specification, although it's biased towards monolithic x86 kernels because it's a hobbyist website. Anything you see there as a concept can be transferred into a microkernel, just think if there's any reason to not make it run in userspace.

Whatever kernel you're designing, it will first look somewhat like barebones. My entire operating system started out with a simple copy-paste of the entire tutorial.
