## What it is
Arnis is a free, open-source desktop application that generates detailed Minecraft Java and Bedrock Edition worlds from real-world geographic data. It uses OpenStreetMap and elevation data to recreate terrain, streets, buildings, and landmarks of any location on Earth.

## Use cases
- generate my hometown in minecraft
- create a minecraft world from real-world map data
- recreate a city like new york or london in minecraft
- build real-world landmarks and buildings in minecraft
- convert openstreetmap data into a playable minecraft world
- generate terrain with accurate elevation in minecraft

## When to choose
- you want to play in a Minecraft world that mirrors a real-world location with high detail
- you need support for both Minecraft Java and Bedrock editions
- you want a free, open-source tool with a user-friendly GUI for selecting areas on a map
- you want to customize generation settings like world scale, spawn point, or building interiors

## When to avoid
- you need a lightweight command-line tool for automated or scripted world generation
- you want to generate worlds on mobile devices without installing anything (use MapSmith instead)
- you need real-time or multiplayer map editing rather than one-shot world generation
