+            ### 🤖 Multi-Agent System Architecture
+            
+            This system uses multiple specialized AI agents working together:
+            
+            **🔗 API Agent**: Fetches real-time market data from multiple sources with fallback mechanisms
+            
+            **📰 Scraping Agent**: Gathers market news and performs sentiment analysis
+            
+            **🗃️ Retriever Agent**: Indexes and retrieves relevant market information
+            
+            **📊 Analysis Agent**: Performs quantitative analysis and risk assessment
+            
+            **🤖 Language Agent**: Synthesizes insights using Google's Gemini AI
+            
+            **🎤 Voice Agent**: Handles speech-to-text and text-to-speech functionality
+            
+            **🎛️ Orchestrator**: Coordinates all agents for comprehensive market analysis
+            
+            ### 🎯 Key Features
+            - Real-time stock data with multiple fallback sources
+            - AI-powered market sentiment analysis
+            - Voice input and output capabilities
+            - Risk assessment and portfolio metrics
+            - Live market updates with caching
+            - Comprehensive market briefs
+            
+            ### 📝 Usage Tips
+            1. Use natural language queries like "How are tech stocks performing?"
+            2. Specify custom stocks or use the default tech portfolio
+            3. Enable voice output for audio briefings
+            4. Use voice input to ask questions hands-free
+            5. Check live updates for real-time monitoring
+            
+            **Note**: This system uses both live market data (when available) and demo data for demonstration purposes.
