 ## Granular Cloud DNS IAM via Service Directory
 
-TODO(ludoo): publish the working example
+<a href="./dns-fine-grained-iam" title="Fine-grained Cloud DNS IAM with Service Directory"><img src="./dns-fine-grained-iam/diagram.png" align="left" width="280px"></a> This [example](./dns-fine-grained-iam) shows how to leverage Service Directory](https://cloud.google.com/blog/products/networking/introducing-service-directory) and Cloud DNS Service Directory private zones, to implement fine-grained IAM controls on DNS.
+
+The example creates a Service Directory namespace with services and endpoints, a Cloud DNS private zone that uses the namespace as its authoritative source, service accounts with different levels of permissions, and VMs to quickly test them.
