## What it is
Hematite is an open-source reimplementation of the Minecraft client written in Rust using the Piston game engine. It can render and fly through a frozen copy of a Minecraft world save, with a Rust-based Minecraft server as a longer-term goal.

## Use cases
- view and fly around a Minecraft world save in Rust
- experiment with a Minecraft client implementation in Rust
- learn game development with the Piston engine
- build a performant alternative Minecraft server in Rust
- study voxel world rendering techniques

## When to choose
- you want a Rust-native, open-source way to explore Minecraft worlds
- you're contributing to or learning from a Piston engine game project
- you need a lightweight voxel renderer for experimentation

## When to avoid
- you want to actually play Minecraft with full interactivity
- you need a production-ready or mod-compatible Minecraft client or server
- you require support for recent Minecraft versions (it targets 1.8.8 world saves)

## Facets
