+    ### 🔧 **Troubleshooting Guide**
+    
+    **If you see errors or long delays:**
+    1. **Wait 60 seconds** between requests (free tier limit)
+    2. **Keep questions short** (under 15 words)
+    3. **Test with "Hello"** first
+    4. **Check API key** in Hugging Face Secrets
+    
+    **Working questions to test:**
+    - "Say hello"
+    - "What is Python?"
+    - "How to declare a variable?"
+    
+    **Model**: `llama-3.2-3b-preview` (Fastest free model)
