 Telemetry.Metrics provides a common interface for defining metrics based on
-[`:telemetry`](https://github.com/beam-telemetry/telemetry) events. See the
+[`:telemetry`](https://github.com/beam-telemetry/telemetry) events. These metrics
+can then be published to different backends using our Reporters API. See the
 [official documentation](https://hexdocs.pm/telemetry_metrics) for more information.
