+# Prerequisites
+
+When seeking to deploy a working openshift cluster using these plays, a few
+items must be in place.
+
+These are:
+
+1) vpc
+2) security group to build the AMI in.
+3) ssh keys to log into instances
+
+These items can be provisioned ahead of time, or you can utilize the plays here
+to create these items.
+
+If you wish to provision these items yourself, or you already have these items
+provisioned and wish to utilize existing components, please refer to
+provisioning_vars.yml.example.
+
+If you wish to have these items created for you, continue with this document.
+
+# Running prerequisites.yml
+
+Warning:  Running these plays will provision items in your AWS account (if not
+present), and you may incur billing charges.  These plays are not suitable
+for the free-tier.
+
+## Step 1:
+Ensure you have specified all the necessary provisioning variables.  See
+provisioning_vars.example.yml and README.md for more information.
+
+## Step 2:
+```
+$ ansible-playbook -i inventory.yml prerequisites.yml -e @provisioning_vars.yml
+```
+
+This will create a VPC, security group, and ssh_key.  These plays are idempotent,
+and multiple runs should result in no additional provisioning of these components.
+
+You can also verify that you will successfully utilize existing components with
+these plays.
