 # Scale cluster
 
 Scaling or reconfiguring your cluster happens on the \"Scale\" tab of
-the CrateDB Cloud Console.

-The page displays the current configuration of your cluster. You can see
-your current plan, the resources of a single node, and the overall
-resources of the cluster.

-You can scale your cluster by clicking the *Edit cluster configuration*

+You can scale your cluster by selecting a different configuration and
+then clicking the **"Scale cluster"** button on the right.
 
 Now you can do three different things:
 
--   Change the plan of your cluster
+-   Change the compute plan of your cluster
 -   Increase storage on each node
 -   Increase/decrease the number of nodes
 
 You can do only one of those operations at a time, i.e., you can\'t
 change plans and scale the number of nodes at the same time.

-:::{note}
-Any promotions or discounts applicable to your cluster will be applied
-to your organization as a whole at the end of the billing period. Due to
-technical limitations, they may not be directly visible in the cluster
-scale pricing shown here, but do not worry! This does not mean that your
-promotion or discount is not functioning.

-:::{warning}
-Storage capacity increases for a given cluster are irreversible. To
-reduce cluster storage capacity, reduce the cluster nodes instead (up to
-a minimum of 2, although we recommend maintaining a minimum of 3 for
-production use).
+:::{caution}
+Storage capacity increases for a cluster are permanent and cannot be reversed.
+To decrease storage capacity, you can either reduce the number of cluster nodes
+(minimum of 2 nodes, though we recommend at least 3 for production environments)
+or start a new cluster with a smaller storage configuration and restore a backup
+to it.
