 [Resource](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/resource/sdk.md)
 is the immutable representation of the entity producing the telemetry.
 If no `Resource` is explicitly configured, the default is to use a resource
 indicating this [Telemetry
 SDK](https://github.com/open-telemetry/opentelemetry-specification/tree/main/specification/resource/semantic_conventions#telemetry-sdk).
-The `SetResourceBuilder` method on `OpenTelemetryLoggerOptions` can be used to
-set a single `ResourceBuilder`. If `SetResourceBuilder` is called multiple
-times, only the last is kept. It is not possible to change the resource builder
+The `ConfigureResource` method on `OpenTelemetryLoggerOptions` can be used to
+configure the `ResourceBuilder`. It is not possible to change the resources
 *after* creating the `LoggerFactory`.
