 ## Design Details
 
-In source-controller we'll add a new predicate for filtering `HelmRepositories` based on the `spec.type` field.
+Unlike the default `HelmRepository`, the OCI `HelmRepository` does not need to
+download any repository index file. The associated HelmChart can pulls the chart
+directly from the OCI registry based on the registry information in the
+`HelmRepository` object. This makes the `HelmRepository` of type `oci` static,
+not backed by a reconciler to move to a desired state. It becomes a data
+container with information about the OCI registry.
 
-The current `HelmRepositoryReconciler` will handle only objects with `type: default`,
-it's scope remains unchanged.
-
-We'll introduce a new reconciler named `HelmRepositoryOCIReconciler`, that will handle
-objects with `type: oci`. This reconciler will set the `HelmRepository` Ready status to
-`False` if:
-- the URL is not prefixed with `oci://`
-- the URL is malformed and can't be parsed
-- the specified credentials result in an authentication error
+In source-controller, the `HelmRepositoryReconciler` will be updated to check
+the `.spec.type` field of `HelmRepository` and do nothing if it is `oci`.
 
 The current `HelmChartReconciler` will be adapted to handle both types.
