+# Terraform Create AWS ACM Certificate For Multiple Domains
+
+The [Terraform documentation for `acm_certificate_validation`](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/acm_certificate_validation) 
+only supports a single domain in the request. This module allows you to support multiple
+domains in the request as long as they are the APEX or *.APEX domain. This will
+reduce code complexity and cost by allowing you to have a single certificate
+with more domains.
