+### OpenTelemetry
+
+Bentocache ships with an official OpenTelemetry package: `@bentocache/otel`.
+It lets you instrument cache operations as spans and integrate with any OpenTelemetry-compatible tracing system (Jaeger, Zipkin, Datadog, New Relic, etc.). You can track cache hits, misses, evictions, and more in your distributed tracing setup.
+
+See the [telemetry documentation](https://bentocache.dev/docs/telemetry) for setup and examples.
+
 ### Friendly TTLs
 
 All TTLs can be passed in a human-readable string format. We use [lukeed/ms](https://github.com/lukeed/ms) under the hood. (this is optional, and you can pass a `number` in milliseconds if you prefer)
