Description - AWS CloudFormation

Description

The Description section (optional) enables you to include comments about your template.

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:

JSON

"Description" : "Here are some details about the template."

YAML

Description: > Here are some details about the template.
