## What it is
A minimalist x86 kernel written in C and assembly that boots via GRUB and prints a message to the screen. It serves as an educational example accompanying a 'Let's write a Kernel' tutorial.

## Use cases
- learn how to write a simple operating system kernel
- understand multiboot kernel booting with GRUB
- test a toy kernel in QEMU
- starting point for hobby OS development
- teach low-level x86 boot process

## When to choose
- you want a minimal, readable example of a bootable x86 kernel
- you are following a tutorial on writing your first kernel
- you need a multiboot-compliant skeleton to build a hobby OS from

## When to avoid
- you need a production or general-purpose operating system
- you want drivers, memory management, or scheduling features
- you need a kernel for non-x86 architectures

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: embedded, developer-tools
- domain: operating-systems, tutorials, education
- platform: cpp, cli
- tags: kernel, x86, bootloader, grub, qemu, educational, linux
