+## 📚 Usage Guide
+
+### Step 1: Index Your Knowledge Base
+
+1. Navigate to the **"Knowledge Base Indexing"** tab
+2. Add URLs of documents you want to index (default includes AI/ML research papers)
+3. Click **"Index Documents"** to process and store in Astra DB
+4. Wait for the indexing process to complete (progress shown in real-time)
+
+### Step 2: Execute Intelligent Queries
+
+1. Switch to the **"Intelligent Query"** tab
+2. Enter your question in the text input
+3. Click **"Execute Query"**
+4. The system will:
+   - Analyze your query
+   - Route to optimal data source (Vector Store or Wikipedia)
+   - Retrieve relevant information
+   - Display results with metadata
+
+### Step 3: Monitor Performance
+
+1. Visit the **"Analytics"** tab to see:
+   - Total queries executed
+   - Routing distribution (Vector Store vs Wikipedia)
+   - Average execution time
+   - Complete query history
+
+---
+
+## 🎓 Example Queries
+
+### Vector Store Queries (Routed to Astra DB)
+```
+✅ "What are the types of agent memory?"
+✅ "Explain chain of thought prompting techniques"
+✅ "How do adversarial attacks work on large language models?"
+✅ "What is ReAct prompting?"
+```
+
+### Wikipedia Queries (Routed to External Search)
+```
+✅ "Who is Elon Musk?"
+✅ "What is quantum computing?"
+✅ "Tell me about the Marvel Avengers"
+✅ "History of artificial intelligence"
+```
