 ## Consequences
 
 - Users will have an additional protocol to be aware of.
-- If the Secret referenced by `ArtifactPullSecret` does not exist, the download will fail.
+- If the Secret referenced by `SecretRef` does not exist, the download will fail.
 - Users need to be notified about different failure types (e.g., unreadable secret, invalid secret).
 - Additional configuration is required to handle authentication, ensuring secure access to resources.
 - We will allow downloads from remote places using self-signed certificates if requested to.
