+
+```bash
+# Serve locally for development
+python3 -m http.server 8080
+# or
+npx serve .
+```
+
+Open `http://localhost:8080` in your browser.
+
+## Android Build
+
+```bash
+# Install dependencies
+npm install
+
+# Copy web assets to Android
+npx cap copy
+
+# Sync Capacitor config
+npx cap sync android
+
+# Open in Android Studio
+npx cap open android
+```
+
+From Android Studio, build and run on a device or emulator.
