title: How to specify parameter definition in CDK stack?
body: <p><a href="https://docs.aws.amazon.com/cdk/latest/guide/get_cfn_param.html" rel="nofollow noreferrer">Use an AWS CloudFormation Parameter</a> section of AWS CDK mentions how to customize your AWS CloudFormation templates. It refers to <strong>CloudFormation template</strong>. I would like to add parameters to my CDK stack and get the parameters section of the synthesized CloudFormation template.</p>
  <p>Do I understand correctly that documentation suggests adding parameters section to synthesized template? If yes, it will be overwritten with every run of <code>cdk synth</code>.</p>
  <p>Any other way to define the parameters section?</p>
