-Upon creating a cluster configuration with `mcad=True` an appwrapper will be created featuring the Ray Cluster and any Routes, Ingresses or Secrets that are needed to be created along side it.<br>
-From there a user can call `cluster.up()` and `cluster.down()` to create and remove the appwrapper thus creating and removing the Ray Cluster.
-
-In cases where `mcad=False` a yaml file will be created with the individual Ray Cluster, Route/Ingress and Secret included.<br>
-The Ray Cluster and service will be created by KubeRay directly and the other components will be individually created.
-
 The `labels={"exampleLabel": "example"}` parameter can be used to apply additional labels to the RayCluster resource.

+After creating their`cluster`, a user can call `cluster.up()` and `cluster.down()` to respectively create or remove the Ray Cluster.
