+## Browser Version (WebAssembly)
+
+PHPBoy can run entirely in your browser using WebAssembly! Play Game Boy games without installing anything.
+
+### Quick Start (Browser)
+
+1. **Build for browser:**
+```bash
+make build-wasm
+```
+
+2. **Serve locally:**
+```bash
+make serve-wasm
+```
+
+3. **Open browser:**
+   - Navigate to `http://localhost:8000`
+   - Click "Choose ROM File" and select a .gb or .gbc ROM
+   - Click "Play" and enjoy!
+
+### Browser Controls
+
+| Key | Game Boy Button |
+|-----|----------------|
+| Arrow Keys | D-Pad |
+| Z | A Button |
+| X | B Button |
+| Enter | Start |
+| Shift | Select |
+
+### Browser Build Commands
+
+- `make build-wasm` - Build WebAssembly version
+- `make serve-wasm` - Serve locally at http://localhost:8000
+- `make wasm-info` - Show WASM build information
+
+### Documentation
+
+- [Browser Usage Guide](docs/browser-usage.md) - How to use PHPBoy in your browser
+- [WASM Build Guide](docs/wasm-build.md) - How to build the WebAssembly version
+- [WASM Options Research](docs/wasm-options.md) - Technical research on PHP-to-WASM approaches
+
+**Note:** The WebAssembly build requires php-wasm (Emscripten-compiled PHP). See [docs/wasm-build.md](docs/wasm-build.md) for setup instructions.
