+## Usage with Manual Instrumentation
+
+It is recommended to use this resource detector with the [OpenTelemetry Autoconfiguration SPI](https://github.com/open-telemetry/opentelemetry-java/blob/main/sdk-extensions/autoconfigure/README.md#resource-provider-spi). The GCP resource detector automatically provides the detected resources via the [autoconfigure-spi](https://github.com/open-telemetry/opentelemetry-java/tree/main/sdk-extensions/autoconfigure-spi) SDK extension.
