 You must already have a VPC setup properly before continuing setting up the stack, it should;
 
 * Have enough IP's available to assign to nodes
 * Be split up into 3 subnets, each in different Availability Zones (AZ's)
 * Provide the VPC ID and associated subnets to the `VPC` and `ServerSubnets` parameters
 
-## Security
+### Contact Email Adress
+
+Supply a valid email address or team/DL alias here.  Cloudwatch alerts will be sent to this address!
+
+* At stack launch time you will receive an email titled `AWS Notification - Subscription Confirmation`
+  * It's important you click the `Confirm subscription` button in this email or else you will not receive notifications
+
+### Security
 
 * You should already have created/uploaded an SSH key to AWS. Provide the keypair name to the `KeyName` parameter
 * If you're using the `main.yaml` stack, you must also create a security group in the referenced VPC to define your administrative access.  Provide sg ID to the `InboundAdminSecurityGroupId` parameter
 
-## Amazon Elasticsearch and Service Linked Role (SLR)
+### Amazon Elasticsearch and Service Linked Role (SLR)
 
 Amazon Elasticsearch requires a specific SLR to be created prior to running this CloudFormation template, specifically one called `AWSServiceRoleForAmazonElasticsearchService`. This role cannot be created programmatically as it is created automatically when setting up a VPC access domain in the AWS console. For more information on this [please see this doc from AWS](https://docs.aws.amazon.com/elasticsearch-service/latest/developerguide/slr-es.html), at this time, even though the doc points to a way to create this manually via the CLI, it still only works via console setup, however AWS adds new features all the time, and by the time you do this, it may work programmatically, please follow their documentation. Once you've created the VPC access domain for AWS ElasticSearch, you can then delete this domain, the role will still be there and you should be able to continue.
