The Description section (optional) enables you to include arbitrary comments about your template. The Description must follow the AWSTemplateFormatVersion section.

The value for the description declaration must be a literal string that is between 0 and 1024 bytes in length. You cannot use a parameter or function to specify the description. The following snippet is an example of a description declaration:
