 ## ✨ Advanced Features
 
-DBChat now includes powerful features for interactive demos, onboarding, and collaborative analysis.
-
-### 🚀 Interactive Demo & Onboarding
-Get started instantly with a guided, interactive experience. DBChat can automatically set up a sample database and walk you through a realistic business scenario.
-- **Guided Workflow**: Instead of typing free-form questions, you'll be presented with multiple-choice options to guide you through data exploration.
-- **Business Narratives**: The demo follows a story, complete with protagonists and goals, making the experience engaging and educational.
-- **Learn by Doing**: Discover database concepts and analytical techniques as you progress through the interactive prompts.
-- **How to start**: Simply connect to DBChat with no database configured (or using the default H2 in-memory database) and type "start demo".
