 To publish a secret stored in GitHub to the cloud as a secure config value with defang, you need to do two things:
 
   1. Use the `env` section of the step to pass the value of the secrets to environment variables that match the names of the config values in your Compose file.
-  2. Specify the names of the environment variables you want to push to the cloud as config values in the `config-env-vars` input.
+  2. Specify the names of the environment variables you want to push to the cloud as config values in the `config-env-vars` input, either whitespace delimited or as a YAML literal block scalar (`|`).
 
 The second step is to make sure that we only publish the secrets you explicitly tell us to. For example, you could have a secret in an env var at the job level, instead of the step level that you might not want to push to the cloud, even if it is in a secure store.
