+Each individual resilience strategy can emit telemetry by using the [`ResiliencePipelineTelemetry`](Telemetry/ResiliencePipelineTelemetry.cs) API. Polly wraps the arguments as [`TelemetryEventArguments`](Telemetry/TelemetryEventArguments.cs) and emits them using `TelemetryListener`.
+To consume the telemetry, Polly adopters needs to assign an instance of `TelemetryListener` to `ResiliencePipelineBuilder.DiagnosticSource` and consume `TelemetryEventArguments`.
 
 For common use-cases, it is anticipated that Polly users would leverage `Polly.Extensions`. This allows all of the aforementioned functionalities by invoking the `ResiliencePipelineBuilder.ConfigureTelemetry(...)` extension method. `ConfigureTelemetry` processes `TelemetryEventArguments` and generates logs and metrics from it.
