 # Configuration
 
-The `cluster-autoscaler` dynamically runs based on tags associated with node
-pools. These are the current valid tags:
-
-```
-k8s-cluster-autoscaler-enabled:true
-k8s-cluster-autoscaler-min:3
-k8s-cluster-autoscaler-max:10
-```
-
-The syntax is in form of `key:value`.
-
-* If `k8s-cluster-autoscaler-enabled:true` is absent or
-  `k8s-cluster-autoscaler-enabled` is **not** set to `true`, the
-  `cluster-autoscaler` will not process the node pool by default.
-* To set the minimum number of nodes to use `k8s-cluster-autoscaler-min`
-* To set the maximum number of nodes to use `k8s-cluster-autoscaler-max`
-
-
-If you don't set the minimum and maximum tags, node pools will have the
-following default limits:
-
-```
-minimum number of nodes: 1
-maximum number of nodes: 200
-```
+Parameters of the autoscaler (such as whether it is on or off, and the
+minimum/maximum values) are configured through the public DOKS API and
+subsequently reflected by the node pool objects. The cloud provider periodically
+picks up the configuration from the API and adjusts the behavior accordingly.
