+- WebDriver connections
+- Screenshot capture
+- JavaScript execution
+- Process monitoring
+
+## 🐳 Docker Configuration
+
+The Dockerfile is optimized for:
+- Minimal image size with multi-stage optimization
+- Proper Chrome dependencies installation
+- Security best practices with non-root user
+- Health checks for reliability
+
+## 📋 Usage Instructions
+
+1. **Start Chrome**: Click "🚀 Start Chrome" to launch the browser instance
+2. **Navigate**: Enter a URL and click "🧭 Navigate" to visit websites
+3. **Screenshot**: Use "📸 Take Screenshot" to capture the current page
+4. **Execute JS**: Use the JavaScript tab to run custom code
+5. **Monitor**: Check status and manage processes as needed
+
+## 🔧 Technical Details

-2. **Headless Chrome**: Optimized for containerized environments
-3. **Screenshot Capture**: Take screenshots of web pages
-4. **URL Navigation**: Navigate to any website
-5. **Process Management**: Safe Chrome process handling
+## 🚨 Troubleshooting
 
-## Usage
+### Common Issues:
 
-1. Click "🚀 Start Chrome" to launch the browser
-2. Use "🧭 Navigate" to go to specific URLs
-3. Click "📸 Take Screenshot" to capture the current page
-4. Use "🛑 Stop Chrome" to terminate all processes
+1. **Chrome won't start**
+   - Check the status output for specific error messages
+   - Ensure sufficient memory is available
+   - Try stopping and restarting Chrome

+   - Ensure the page has finished loading
+   - Check if the target URL is accessible
 
-- Chrome runs in headless mode with remote debugging enabled
-- Uses Selenium WebDriver for automation
-- Optimized Chrome flags for containerized environments
-- Proper error handling and resource cleanup
+3. **JavaScript execution errors**
+   - Verify the JavaScript syntax
+   - Ensure Chrome is running and has a page loaded
+   - Check browser console for additional error details
 
-## Troubleshooting
+### Performance Tips:
+- Keep Chrome running between operations for better performance
+- Use the status check before taking screenshots
+- Clean up processes periodically if running long sessions
 
-If you encounter issues:
+## 🔒 Security Notes
 
-1. **Chrome won't start**: Check the status output for error messages
-2. **Screenshots fail**: Ensure Chrome is running first
-3. **Navigation issues**: Verify the URL format (add https:// if needed)
+- Runs in a sandboxed container environment
