 Tests Kraft cluster operations:
 
 - Cluster stop/pause/restart
 - Scale brokers up/down
 - Scale controllers up/down
 
-TODO:
+Notes
 
+- Kafka 3.7 controllers do not scale at all.
+  The scaling test steps are disabled for this version.
 - Scaling controllers from 3 -> 1 doesn't work.
   Both brokers and controllers try to communicate with old controllers.
   This is why, the last step scales from 5 -> 3 controllers.
