+```
+
+## Usage Examples
+
+### Example Automation Tasks
+```
+"Navigate to Google and search for 'Browser.AI automation'"

+"Open LinkedIn, update my headline to 'AI Automation Expert'"
+"Go to Hacker News and get the top 5 stories"
+```
+
+### API Usage
+```python
+import requests
+
+# Create task
+response = requests.post("http://localhost:8000/tasks/create", json={
+    "description": "Search Google for Browser.AI",
+    "config": {
+        "llm": {"provider": "openai", "model": "gpt-4"},
+        "browser": {"headless": True}
+    }
+})
+
+task_id = response.json()["task_id"]
+
+# Start task
+requests.post(f"http://localhost:8000/tasks/{task_id}/start")
+```

+## Integration Points
+
+### Browser.AI Integration
+- **Non-intrusive**: No modifications to existing Browser.AI code
+- **Event-driven**: Captures logs via custom logging handlers
+- **Task Orchestration**: Wraps Browser.AI Agent execution
+- **Configuration**: Seamless LLM provider integration
+
+### WebSocket Events
+- `log_event`: Real-time log streaming
+- `task_started`: Task initiation notification
+- `task_completed`: Task completion with results
+- `task_stopped`: User-initiated task cancellation
+- `error`: Error notifications
+
+## Development Notes
+
+### Best Practices Followed
+- **Separation of Concerns**: Clear boundaries between components
+- **Error Handling**: Comprehensive exception handling
+- **Async/Await**: Non-blocking operations throughout
