 ## Deploy DC/OS
 
-### Deploying with Default Configuration
-
-We've provided sensible defaults if you would want to play around with Mesosphere DC/OS. The default variables are tracked in  [variables.tf](/aws/variables.tf). 
-
-Just run this command to deploy a multi-master setup in the cloud. **3 agents will be deployed** for you; 2 private agents, 1 public agent.
-
-```bash
-terraform apply 
-```
-
 ### Deploying with Custom Configuration
 
 The default variables are tracked in the [variables.tf](/aws/variables.tf) file. Since this file can be overwritten during updates when you may run `terraform get --update` when you fetch new releases of DC/OS to upgrade to, it's best to use the [desired_cluster_profile.tfvars](/aws/desired_cluster_profile.tfvars.example) and set your custom Terraform and DC/OS flags there. This way you can keep track of a single file that you can use manage the lifecycle of your cluster.
