+2. Choose "BBC News"
+3. Click "Analyze News Site"
+4. Repeat with other sites for comparison
+
+## 🛠️ Customization Options
+
+### Adding New News Sites
+Edit the `news_sites` dictionary in `app.py`:
+```python
+news_sites = {
+    "BBC News": "https://www.bbc.com/news",
+    "Reuters": "https://www.reuters.com",
+    "Your Site": "https://yoursite.com"
+}
+```
+
+### Adjusting Detection Weights
+Modify the weights in the `calculate_ai_probability` method:
+```python
+weights = {
+    'perplexity_score': 0.2,      # 20%
+    'burstiness_score': 0.15,     # 15%
+    'vocab_diversity_score': 0.15, # 15%
+    'repetitive_patterns_score': 0.2, # 20%
+    'sentence_structure_score': 0.1,  # 10%
+    'readability_score': 0.1,     # 10%
+    'semantic_coherence_score': 0.1   # 10%
+}
+```
