 ### Tailor does not recognize a certain resource kind
 
-Tailor currently supports `BuildConfig`, `CronJob`, `Job`, `Deployment`, `DeploymentConfig`, `ImageStream`, `LimitRange`, `PersistentVolumeClaim`, `ResourceQuota`, `RoleBinding`, `Route`, `Secret`, `Service`, `ServiceAccount`, `Template`, `HorizontalPodAutoscaler`. Some resources like `Build`, `Event`, `ImageStreamImage`, `ImageStreamTag`, `PersistentVolume`, `Pod`, `ReplicationController` are not supported by design as they are created and managed automatically by OpenShift. If you want to control a resource with Tailor that is not supported yet, but would be suitable, please [open an issue](https://github.com/opendevstack/tailor/issues/new).
