 # Cluster Autoscaler on Huawei Cloud 
 
 ## Overview
-The cluster autoscaler for [Huawei Cloud](https://www.huaweicloud.com/) scales worker nodes within any
-specified Huawei Cloud Container Engine (CCE) cluster's node pool where the `Autoscaler` label is on. 
+The cluster autoscaler for [Huawei ServiceStage](https://www.huaweicloud.com/intl/en-us/product/servicestage.html) scales worker nodes within any
+specified container cluster's node pool where the `Autoscaler` label is on. 
 It runs as a Deployment on a worker node in the cluster. This README will go over some of the necessary steps required 
 to get the cluster autoscaler up and running.
 
 Note: 
 
-1. Cluster autoscaler must be run on CCE v1.15.6 (Kubernetes v1.15) or later.
-2. Node pool attached to the CCE cluster must have the `Autoscaler` flag turned on, and minimum number of nodes and maximum
-number of nodes being set. Node pools can be managed under `Resource Management` in CCE console.

 3. If warnings about installing `autoscaler addon` are encountered after creating a node pool with `Autoscaler` flag on, 
 just ignore this warning and DO NOT install the addon.
 4. Do not build your image in a Huawei Cloud ECS. Build the image in a machine that has access to the Google Container Registry (GCR).
