 === Metrics
 
-If you're using https://micrometer.io/[MicroMeter's] Quarkiverse OTLP registry to push metrics to Grafana OTel LGTM, this is how you would define the export endpoint url; where `quarkus.otel-collector.url` is provided by the Observability Dev Services extension.
+If you need metrics, add the Micrometer OTLP registry to your build file:

-In this case LGTM Dev Resource would be automatically started and used by Observability Dev Services.
