+# Demo of Integrating the native Azure Pulumi provider with the Microsoft Azure SDK
+
+The native Azure Pulumi provider exposes the entire resource model of Azure Resource Manager. Each resource can be created, updated, deleted, or refreshed (read).
+
+However, Azure API has many endpoints that don't map to our resource model. For examples, finding resources given some filter criteria is not supported directly.
+
+However, you can easily integrate an Azure SDK call inside your Pulumi program using the same programming language. We provide a helper function `authorization.GetClientToken()` that returns a valid authentication token for the same login context that the Pulumi provider is using.
+
+This example demonstrates how to use such integration to lookup a role definition ID based on its name and scope. It then creates a role assignment for the resulting definition to allow pulling container images from a registry.
+
+## Running the App
+
+1.  Create a new stack:
+
+    ```
+    $ pulumi stack init dev
+    ```
+
+1.  Login to Azure CLI (you will be prompted to do this during deployment if you forget this step):
+
+    ```
+    $ az login
+    ```
+
+1. Set the Azure region location to use:
+
+    ```
+    $ pulumi config set azure-native:location WestUS
+    ```
+
+1.  Run `pulumi up` to preview and deploy changes:
+
+    ``` 
+    $ pulumi up
+    Previewing changes:
+    ...
+    Performing changes:
+    ...
+    Resources:
+        ~ 1 updated
+        3 unchanged
+    ```
