 The following diagram shows how KubeDB Autoscaler operator autoscales the resources of `MongoDB` database components. Open the image in a new tab to see the enlarged version.

 The Auto Scaling process consists of the following steps:
 
 1. At first, a user creates a `MongoDB` Custom Resource Object (CRO).
 
-2. `KubeDB` Community operator watches the `MongoDB` CRO.
+2. `KubeDB` Provisioner  operator watches the `MongoDB` CRO.
 
 3. When the operator finds a `MongoDB` CRO, it creates required number of `StatefulSets` and related necessary stuff like secrets, services, etc.
 
 4. Then, in order to set up autoscaling of the various components (ie. ReplicaSet, Shard, ConfigServer, Mongos, etc.) of the `MongoDB` database the user creates a `MongoDBAutoscaler` CRO with desired configuration.
 
 5. `KubeDB` Autoscaler operator watches the `MongoDBAutoscaler` CRO.
 
-6. `KubeDB` Autoscaler operator creates required number of Vertical Pod Autoscaler [VPA](https://github.com/kubernetes/autoscaler/tree/master/vertical-pod-autoscaler#intro) for different components of the database, as specified in the `mongodbautoscaler` CRO.
+6. `KubeDB` Autoscaler operator generates recommendation using the modified version of kubernetes [official recommender](https://github.com/kubernetes/autoscaler/tree/master/vertical-pod-autoscaler/pkg/recommender) for different components of the database, as specified in the `MongoDBAutoscaler` CRO.
 
-7. Then `KubeDB` Autoscaler operator continuously watches the VPA objects for recommendation.
+7. If the generated recommendation doesn't match the current resources of the database, then `KubeDB` Autoscaler operator creates a `MongoDBOpsRequest` CRO to scale the database to match the recommendation generated.
 
-8. If the VPA generated recommendation doesn't match the current resources of the database, then `KubeDB` Autoscaler operator creates a `MongoDBOpsRequest` CRO to scale the database to match the recommendation provided by the VPA object.
+8. `KubeDB` Ops-manager operator watches the `MongoDBOpsRequest` CRO.
 
-9. `KubeDB` Enterprise operator watches the `MongoDBOpsRequest` CRO.
-
-10. Then the `KubeDB` Enterprise operator will scale the database component vertically as specified on the `MongoDBOpsRequest` CRO.
+9. Then the `KubeDB` Ops-manager operator will scale the database component vertically as specified on the `MongoDBOpsRequest` CRO.
 
 In the next docs, we are going to show a step by step guide on Autoscaling of various MongoDB database components using `MongoDBAutoscaler` CRD.
