 It provides a bean of type `OpenTelemetry`, and if there are beans of type `SdkTracerProvider`, `ContextPropagators`, `SdkLoggerProvider` or `SdkMeterProvider` in the application context, they automatically get registered.
 Additionally, it provides a `Resource` bean.
-The attributes of the `Resource` can be configured via the configprop:management.opentelemetry.resource-attributes[] configuration property.
+The attributes of the auto-configured `Resource` can be configured via the configprop:management.opentelemetry.resource-attributes[] configuration property.
+If you have defined your own `Resource` bean, this will no longer be the case.
 
 NOTE: Spring Boot does not provide auto-configuration for OpenTelemetry metrics or logging.
 OpenTelemetry tracing is only auto-configured when used together with <<actuator#actuator.micrometer-tracing, Micrometer Tracing>>.
