-# ghostty-wasm
+# WASM Terminal - xterm.js Compatible
+
+A minimal terminal emulator with an xterm.js-compatible API, built with:
+- **TypeScript** for terminal state management and rendering
+- **Zig + WASM** for low-level parsing helpers (optional)
+- **libghostty-vt inspiration** (though current implementation is self-contained)
+
+## Status: Proof of Concept (PoC)
+
+This is a janky, experimental implementation to explore using libghostty-vt with WASM.
+
+## Structure
+
+```
+wasm-terminal/
+├── zig/                    # Zig WASM module
+│   ├── build.zig          # Zig build configuration
+│   ├── main.zig           # WASM exports (helper functions)
+│   └── zig-out/bin/       # Compiled WASM binary
+├── src/
+│   └── terminal.ts        # TypeScript terminal implementation
+├── index.html             # Demo page
+└── README.md
+```
+
+## Building
+
+```bash
+# Build WASM module (requires Zig 0.13.0)
+cd zig
+zig build
+
+# Open demo
+# Serve index.html with any HTTP server, e.g.:
+python3 -m http.server 8000
+# Then open http://localhost:8000
+```
+
+## API Compatibility
+
+Implements core xterm.js Terminal API:
+- `new Terminal(options)`
+- `open(parent)`
+- `write(data)`
+- `resize(cols, rows)`
+- `clear()`
+- `dispose()`
+- `onData` event
+- `onResize` event
+
+## Current Limitations
+
+- No ANSI color parsing yet (cell attributes exist, not implemented)
+- No selection/clipboard support
+- No addons support
+- Basic rendering (no canvas/webgl)
+- WASM module is minimal (just helper functions)
+
+## Next Steps
+
+To make this production-ready:
+1. Add full ANSI/VT escape sequence parsing
+2. Implement color rendering (SGR sequences)
+3. Add cursor rendering and styles
+4. Integrate actual libghostty-vt WASM builds
+5. Performance optimization
+6. Selection and clipboard support
+7. Scrollback buffer management
