## What it is
Mitchell Hashimoto's personal NixOS system configurations, written in Nix. It documents a macOS host + NixOS VM development workflow and serves as a reference for declarative system setup.

## Use cases
- learn how to structure a NixOS configuration
- set up NixOS in a VM on macOS for development
- reference examples of declarative Linux system setup
- see how an experienced developer organizes Nix modules
- configure a shared-folder and networking setup between macOS host and Linux VM

## When to choose
- you want a real-world, well-maintained example of NixOS configuration to learn from
- you run macOS and want a Linux dev environment in a VM
- you know Nix basics and want patterns to copy into your own config

## When to avoid
- you want a turnkey, plug-and-play NixOS setup
- you are a complete beginner expecting a tutorial
- you need a supported, general-purpose configuration framework rather than one person's personal setup

- function: configuration-management, developer-tools
