+Moreover, it has undergone breaking changes and is no longer functioning as intended.
+As a result, Kubebuilder, which heavily relies on the Controller Runtime, has also deprecated this feature,

 This tutorial will show you how to create a custom configuration file for your
 project by modifying a project generated with the `--component-config` flag
 passed to the `init` command. The full tutorial's source can be found

 Now that you have a component config base project we need to customize the
 values that are passed into the controller, to do this we can take a look at 
 `config/manager/controller_manager_config.yaml`.
