 |By default, each cluster creates the following instances:
 
-* One `m4.large` bootstrap machine, which is removed after installation
-* Three `m4.xlarge` master nodes
-* Three `m4.large` worker nodes
+* One bootstrap machine, which is removed after installation
+* Three master nodes
+* Three worker nodes
 
 These instance type counts are within a new account's default limit. To deploy
 more worker nodes, enable autoscaling, deploy large workloads, or use a
 different instance type, review your account limits to ensure that your cluster
 can deploy the machines that you need.
 
+In most regions, the bootstrap machine uses an `m4.large` machine and the
+master and worker machines use `m4.xlarge` machines. If these machine types
+are not available in the region that you select, `m5.large` and `m5.xlarge`
+machines are used instead.
