 ## Usage
 
+### Demo Mode
+
+For testing and demonstration purposes, you can run the interactive demo:
+
+```bash
+# Run interactive demo (simulates scraping with fake data)
+npm run demo
+
+# Or directly:
+node demo.js
+```
+
+The demo mode:
+
+- Uses fake, anonymized data for safety
+- Walks through all configuration options interactively
+- Shows available Ollama models for selection
+- Demonstrates the complete workflow without actual LinkedIn scraping
+- Perfect for creating documentation, GIFs, or testing configurations
+
