        CidrIp: {{ my_home_IP }}/32
        Description: "SSH from home"

Step 2. Import from CloudFront

I did it from browser. After uploading the template, I need to specify which resouces in definition corresponds to which real resources.

After CloudFront imported the configuration, you can see that several tags are added to the resouces, like aws:cloudformation:stack-id, aws:cloudformation:stack-name, and aws:cloudformation:logical-id.
