+# Validate a minimum operating system version
+
+This example uses the `Microsoft/OSInfo` resource with the `Microsoft.DSC/Assertion` group
+resource to verify that the operating system version meets a minimum requirement before DSC runs
+another resource.
+
+> [!IMPORTANT]
+> The `osinfo` command and `Microsoft/OSInfo` resource are a proof-of-concept example for use with
+> DSC. Don't use it in production.
+
+## Definition
+
+The **Operating System Assertion** group contains a `Microsoft/OSInfo` resource instance with the
+version constraint `>= 10.0`. The `Microsoft.DSC/Assertion` resource always invokes **Test** for
+nested instances. If the operating system is earlier than version `10.0`, the configuration fails
+and DSC doesn't invoke **Show operating system**.
+
+:::code language="yaml" source="validate-minimum-version.config.dsc.yaml":::
+
+## Running the configuration
+
+Run the configuration with the [dsc config set][01] command:
+
+```bash
+dsc config set --file ./validate-minimum-version.config.dsc.yaml
+```
+
+On an operating system whose version is at least `10.0`, DSC returns successful results for both
+the assertion group and the dependent echo resource:
+
+```yaml

 [dsc resource test][02] command, input JSON representing the desired state of the instance is
 required. The JSON must define at least one instance property to validate.
 
-The resource doesn't implement the [test operation][03]. It relies on the synthetic testing feature
-of DSC instead. The synthetic test uses a case-sensitive equivalency comparison between the actual
-state of the instance properties and the desired state. If any property value isn't an exact match,
-DSC considers the instance to be out of the desired state.
+The resource implements the [test operation][03]. The command passes the desired state to the
+resource over stdin and the resource returns the actual operating system information with an
+`_inDesiredState` value. DSC returns that value as `inDesiredState` in the test result.
+
+All properties except `version` use case-sensitive equality comparison. For `version`, you can use
+an exact version or a constraint with `>`, `<`, `=`, `>=`, or `<=`. For more information, see the
+[version property][04] reference.
