+## 🔧 Configuration Details
+
+### Dependabot Configuration
+
+The `dependabot.yml` file configures automated dependency updates:
+
+- **Gradle dependencies**: Weekly updates on Monday at 2:00 AM UTC
+- **GitHub Actions**: Weekly updates on Monday at 2:30 AM UTC
+- **Intelligent grouping**: Kotlin-related updates are grouped together
+- **Version constraints**: Major Kotlin updates are ignored for stability
+- **Proper labeling**: All PRs are labeled appropriately for easy identification
+
+### Environment Variables and Secrets
+
+The workflows use the following environment variables and secrets:
+
+| Variable/Secret | Usage | Required |
+|----------------|-------|----------|
+| `GITHUB_TOKEN` | GitHub API access for releases and comments | ✅ Auto-provided |
+| `GRADLE_OPTS` | Gradle optimization settings | ✅ Set in workflows |
+
+### Performance Thresholds
+
+The performance monitoring workflow uses these thresholds:
+
+| Metric | Threshold | Status |
+|--------|-----------|--------|
+| Clean Build | < 2 minutes (120s) | ✅ Good / ⚠️ Slow |
+| Incremental Build | < 30 seconds | ✅ Good / ⚠️ Slow |
+| Test Execution | < 1 minute (60s) | ✅ Good / ⚠️ Slow |
+| WASM Build | < 1.5 minutes (90s) | ✅ Good / ⚠️ Slow |
+

+# OSM Maker - WebAssembly Demo
+
+This project demonstrates a Kotlin application compiled to WebAssembly (WASM) that processes OpenStreetMap (OSM) data.
+
+## Files
+
+- `demo.html` - The main HTML demo file
+- `build/dist/wasmJs/developmentExecutable/` - Contains the compiled WASM artifacts:
+  - `osm-maker.js` - JavaScript wrapper for the WASM module
+  - `db8d653255edcefb8149.wasm` - The WebAssembly binary
+
+## How to Run the Demo
+
+### Option 1: Using Python HTTP Server (Recommended)
+
+1. Open a terminal in the project root directory
+2. Start a local HTTP server:
+   ```bash
+   python3 -m http.server 8080
+   ```
+   Or if you have Python 2:
+   ```bash
+   python -m SimpleHTTPServer 8080
+   ```
+
+3. Open your web browser and navigate to:
+   ```
+   http://localhost:8080/demo.html
+   ```
+
+### Option 2: Using Node.js HTTP Server
+
+1. Install a simple HTTP server globally:
+   ```bash
+   npm install -g http-server
+   ```
+
+2. Run the server in the project directory:
+   ```bash
+   http-server -p 8080
+   ```
+
+3. Open your browser to `http://localhost:8080/demo.html`
+
+### Option 3: Using Live Server (VS Code Extension)
+
+1. Install the "Live Server" extension in VS Code
+2. Right-click on `demo.html` and select "Open with Live Server"
+
+## What the Demo Does
+
+The demo showcases a simplified version of OSM data processing:
+
+1. **Location**: Processes data for Poquoson, Virginia (bounding box: 37.115,-76.396,37.139,-76.345)
+2. **Functionality**: 
+   - Parses geographic coordinates
+   - Calculates approximate area
+   - Demonstrates WASM compilation success
+3. **Output**: Displays processing results in a browser-friendly interface
+
+## Demo Features
+
+- 🗺️ **Interactive Interface**: Clean, professional web interface
+- 📍 **Geographic Processing**: Demonstrates coordinate parsing and calculations
+- 🚀 **WASM Integration**: Shows successful Kotlin-to-WASM compilation
+- 🖥️ **Console Output**: Captures and displays WASM output in the browser
+- ⚡ **Real-time Feedback**: Status indicators and error handling
+
+## Technical Details
+
+- **Source**: Kotlin multiplatform project with WASM target
+- **Build Tool**: Gradle with Kotlin multiplatform plugin
+- **WASM Size**: ~543 KiB
+- **JavaScript Wrapper**: ~57 KiB
+- **Browser Compatibility**: Modern browsers with WASM support
+
+## Troubleshooting
+
+### CORS Issues
+If you see CORS-related errors, make sure you're serving the files through an HTTP server rather than opening the HTML file directly in the browser.
+
+### Module Loading Issues
+If the WASM module fails to load:
+1. Check that all files are in the correct locations
+2. Ensure your browser supports WebAssembly
+3. Check the browser console for detailed error messages
+
+### No Output
+If the demo runs but shows no output:
+1. The main function might execute automatically during module initialization
+2. Check the browser's developer console for any logged output
+3. The fallback simulation should still demonstrate the expected functionality
+
+## Building from Source
+
+To rebuild the WASM artifacts:
+
+```bash
+./gradlew wasmJsBrowserDevelopmentExecutableDistribution
+```
+
+This will regenerate the files in `build/dist/wasmJs/developmentExecutable/`.
+
+## Browser Support
+
+The demo requires a modern browser with WebAssembly support:
+- Chrome 57+
+- Firefox 52+
+- Safari 11+
+- Edge 16+
+
+## Next Steps
+
+This demo provides a foundation for more complex WASM applications. Potential enhancements:
+
+1. **Real OSM Data**: Integrate with Overpass API for live data
+2. **3D Visualization**: Add WebGL rendering for 3D geometry
+3. **Interactive Maps**: Integrate with mapping libraries like Leaflet
+4. **Performance Metrics**: Add timing and memory usage statistics
