What is this?

Installing this tool will provide you with the command cfn-docs.

The command cfn-docs accepts an AWS CloudFormation template and returns a description of the template in markdown:

cfn-docs org-bootstrap.template.yaml > org-bootstrap.template.README.md

In the example above we redirect the std out into a file.

What does it read?

The tool will read the description from the template, each parameter, each resource and each output. It will output those descriptions in a markdown document under suitable headers. It also lists parameters, resources and outputs that do not have any descriptions.
