+If the platform environment supports the templating feature of coreos-cloudinit it is possible to automate etcd configuration with the `$private_ipv4` and `$public_ipv4` fields. When generating a [discovery token](https://discovery.etcd.io/new?size=3), set the `size` parameter, since etcd uses this to determine if all members have joined the cluster. After the cluster is bootstrapped, it can grow or shrink from this configured size.
+
+For example, the following cloud-config document...
 
 ```yaml
 #cloud-config
 
 coreos:
   etcd2:
-    # generate a new token for each unique cluster from https://discovery.etcd.io/new
+    # generate a new token for each unique cluster from https://discovery.etcd.io/new?size=3
     discovery: https://discovery.etcd.io/<token>
     # multi-region and multi-cloud deployments need to use $public_ipv4
