-### Tracking support
-
-The Unleash provider supports OpenFeature tracking for A/B testing and analytics:
-
-```python
-from openfeature.evaluation_context import EvaluationContext
-
-# Basic tracking
-provider.track("page_view")
-
-# Tracking with context
-context = EvaluationContext(
-    targeting_key="user123",
-    attributes={"email": "[email protected]", "country": "US"}
-)
-provider.track("button_click", context)
-
-# Tracking with event details
-event_details = {
-    "value": 99.99,
-    "currency": "USD",
-    "category": "purchase"
-}
-provider.track("purchase_completed", event_details=event_details)
-
-# Tracking with both context and details
-provider.track("conversion", context, event_details)
-```

-**Tracking features:**
-- **Event Names**: Track user actions or application states
-- **Evaluation Context**: Include user targeting information
-- **Event Details**: Add numeric values and custom fields for analytics
