+## Adding a Rocky Linux 9 software stack
+
+RES does not have a default software stack for Rocky Linux 9, so this section offers a recommendation on which Rocky AMI to use and how to use it.
+
+  1. Log into the AWS Console, and go to the [AMI Catalog page](https://console.aws.amazon.com/ec2/home#AMICatalog) within the EC2 Console.
+
+  2. Search for AMIs under the **AWS Marketplace** tab with the name **Rocky Linux 9**.
+
+  3. Select the AMI named **Rocky Linux 9 (Official) - x86_64** from **Rocky Linux**.
+
+![](/images/res/archive/release-minus-3/ug/images/res-rocky-linux9.png)
+
+  4. Once selected, choose **Subscribe now**.
+
+  5. Scroll up, and copy the AMI Id for **Selected AMI**.
+
+![](/images/res/archive/release-minus-3/ug/images/res-ami-catalog.png)
