 It's in very early stages of development and is a basis for a larger envisioned system. The progress is fairly slow, only allowed as my available time permits.

+The kernel is in very early stages of development, while I am building up tooling support to make future development fast and painless. This is my second post here and as usual, I will link directly to my blog for more details. [Read the full article here](https://metta.systems/blog/osdev-tooling-2/).
