-The secret value is mapped to the secret name declared at the application level as described in the [defining secrets](#defining-secrets) section.    The `passwordSecretRef` and `secretref` parameters are used to reference the secret names as environment variables at the container level.  The `passwordSecretRef` provides a descriptive parameter name for secrets containing passwords.
+After declaring secrets at the application level as described in the [defining secrets](#defining-secrets) section, you can reference them in environment variables when you create a new revision in your container app. When an environment variable references a secret, its value is populated with the value defined in the secret.
 
 ## Example
 
-The following example shows an application that declares a connection string at the application level and is used throughout the configuration via `secretref`.
