+The `CLUSTER ADDSLOTSRANGE` is similar to the `CLUSTER ADDSLOTS` command in that they both assign hash slots to nodes.
+
+The difference between the two commands is that `ADDSLOTS` takes a list of slots to assign to the node, while `ADDSLOTSRANGE` takes a list of slot ranges (specified by start and end slots) to assign to the node.
+
+## Example
+
+To assign slots 1 2 3 4 5 to the node, the `ADDSLOTS` command is:
+
+    > CLUSTER ADDSLOTS 1 2 3 4 5
+    OK
+
+The same operation can be completed with the following `ADDSLOTSRANGE` command:
+
+    > CLUSTER ADDSLOTSRANGE 1 5
+    OK
+
+
+## Usage in Redis Cluster
+
+This command only works in cluster mode and is useful in the following Redis Cluster operations:
+
+1. To create a new cluster ADDSLOTSRANGE is used in order to initially setup master nodes splitting the available hash slots among them.
+2. In order to fix a broken cluster where certain slots are unassigned.
+
+@return
+
+@simple-string-reply: `OK` if the command was successful. Otherwise an error is returned.
