-# Terraform <NAME>
+# Terraform AWS Central DNS
 
 ## Description
 
-Add a description of the module here
+This purpose of this module is to manage and provision a central DNS solution with an AWS estate. Under this setup all private hosted zones defined within the spoke accounts have the ability to perform DNS resolution between them.
 
 ## Usage
 
-Add example usage here
