+### Resource Provider SPI
+
+The [autoconfigure-spi](https://github.com/open-telemetry/opentelemetry-java/tree/main/sdk-extensions/autoconfigure-spi),
+part of the SDK extensions, provides a convenient ResourceProvider SPI that adds
+[common resource attributes](https://github.com/open-telemetry/opentelemetry-java/tree/main/sdk-extensions/resources) automatically. The SDK extensions include a [predefined set of common resources](https://github.com/open-telemetry/opentelemetry-java/blob/main/sdk-extensions/resources/src/main/resources/META-INF/services/io.opentelemetry.sdk.autoconfigure.spi.ResourceProvider),
+[common cloud vendor resources](https://github.com/open-telemetry/opentelemetry-java/blob/main/sdk-extensions/aws/src/main/resources/META-INF/services/io.opentelemetry.sdk.autoconfigure.spi.ResourceProvider),
+or you can create your own.
+
+### Disabling Automatic ResourceProviders
+
+If you are using the `ResourceProvider` SPI (many instrumentation agent distributions include this automatically),
+you can disable one or more of them by using the following configuration item:
+
+| System property                       | Environment variable                  | Description                                                                        |
+|---------------------------------------|---------------------------------------|------------------------------------------------------------------------------------|
+| otel.java.disabled.resource-providers | OTEL_JAVA_DISABLED_RESOURCE_PROVIDERS | Disables one or more `ResourceProvider` types |
+
+The value must be a comma separated list of fully qualified `ResourceProvider` classnames.
+For example, if you don't want to expose the name of the operating system through the resource, you
+can pass the following JVM argument:
+
+```
+-Dotel.java.disabled.resource-providers=io.opentelemetry.sdk.extension.resources.OsResourceProvider
+```
