## What it is
Minoca OS is a general-purpose operating system written from scratch in C, featuring a POSIX-like interface, an event-driven preemptive SMP kernel, and a forward-compatible driver model. It runs on x86 PCs and a range of ARM boards and ships with a growing suite of prebuilt packages.

## Use cases
- run a lightweight POSIX-like OS on ARM boards
- study how an operating system kernel is built from scratch
- develop kernel drivers with a forward-compatible driver model
- build custom OS images for x86 or ARM hardware
- experiment with an SMP, network-capable hobby OS

## When to choose
- you want a small, maintainable OS codebase to learn from or modify
- you need a POSIX-like environment on ARM boards like Raspberry Pi
- you want to write kernel drivers without recompiling them on every kernel upgrade

## When to avoid
- you need a production-grade OS with broad hardware support and long-term security updates
- you require a large package ecosystem or mainstream community support
- you need support for architectures beyond x86 and ARMv6/ARMv7

## Facets
