 Cake.Recipe is driven by [environment variables](./environment-variables).  These are used to store the sensitive information that is required during the build process.  For example, the username and password needed to send email, or the token required to access GitHub.
 
-Cake.Recipe has default environment variable names for all the pieces of information that are required.  The expectation is that either locally on your own machine, or on the CI/CD pipeline that you are using, you set the values for all of the ones that you intend to use.
