+Scheduler Mode
+--------------
+
+The scheduler mode controls how HA selects nodes during recovery of a service.
+The default mode is `basic`, you can change it in `datacenter.cfg`:
+
+----
+crs: ha=static
+----
+
+For each service that needs to be recovered, the scheduler iteratively chooses
+the best node among the nodes with the highest priority in the service's group.
+
+NOTE: There are plans to add modes for (static and dynamic) load-balancing in
+the future.
+
+Basic
+^^^^^
+
+The number of active HA serivces on each node is used to choose a recovery node.
+
+Static
+^^^^^^
+
+Static usage information from HA serivces on each node is used to choose a
+recovery node. In particular, CPU and memory configuration is considered.
