# 🐢 Honu

LOGO-style turtle graphics powered by Shrimp.

## Quickstart

```bash
bun install
bun dev
```

Open http://localhost:3002

This builds the app and serves the `dist/` folder with Python's built-in HTTP server.

## Building

```bash
bun run build
```

Outputs a bundled browser app to `dist/`. The `dist/` folder contains:

- `index.html` - The main page
- `app.js` - Bundled JavaScript (Parser + Compiler + ReefVM + CodeMirror)

You can serve the `dist/` folder with any static file server, or even open `index.html` directly in a browser.
