     from an existing Terraform module (also new in 0.3).
   * Terraform will ask for user input to fill in required variables and
     provider configurations if they aren't set.
+  * `terraform apply MODULE` can be used as a shorthand to quickly build
+    infrastructure from a module.
   * The state file format is now JSON rather than binary. This allows for
     easier machine and human read/write. Old binary state files will be
     automatically upgraded.
