+## OpenTelemetry Support
+
+**taskiq-faststream** supports distributed tracing with OpenTelemetry. To enable it, install the `otel` extra and pass `enable_otel=True` when creating the broker wrapper:
+
+```python
+from faststream.nats import NatsBroker
+from taskiq_faststream import BrokerWrapper
+
+broker = NatsBroker()
+
+# Enable OpenTelemetry middleware
+taskiq_broker = BrokerWrapper(broker, enable_otel=True)
+```
+
+This will automatically add OpenTelemetry middleware to track task execution, providing insights into:
+- Task execution spans
+- Task dependencies and call chains
+- Performance metrics
+- Error tracking
+
+Make sure to configure your OpenTelemetry exporter (e.g., Jaeger, Zipkin) according to your monitoring setup.
+
+The same applies to `AppWrapper`:
+
+```python
+from faststream import FastStream
+from taskiq_faststream import AppWrapper
+
+app = FastStream(broker)
+
+# Enable OpenTelemetry middleware
+taskiq_broker = AppWrapper(app, enable_otel=True)
+```
