+## Step 4/4. Enroll your infrastructure
 
-Servers you have registered with Teleport record the commands that users execute
-during their sessions so operators can play them back later to investigate
-issues.
+With Teleport, you can protect all of the resources in your infrastructure
+behind a single identity-aware access proxy, including servers, databases,
+applications, Kubernetes clusters, Windows desktops, and cloud provider APIs.

-### Add resources
+Now that you have launched your Teleport cluster and added your first resources,
+see how to use Teleport to set up secure access to your infrastructure. 
 
-Now that you know how to set up a Teleport cluster, learn how to register all of the
-resources in your infrastructure with Teleport:
