 ## Examples
 
+### Basic example which uses PUT method and payload encoded as form data
+
+This example implements 2 REST commands to add service calls for the missing shuffle functionality of the iTunes integration.
+
+```yaml
+rest_command:
+  shuffle_on: 
+    url: "http://YOUR_ITUNES-API_SERVER_IP:8181/shuffle"
+    method: put
+    content_type: "application/x-www-form-urlencoded"
+    payload: "mode=songs"
+  shuffle_off: 
+    url: "http://YOUR_ITUNES-API_SERVER_IP:8181/shuffle"
+    method: put
+    content_type: "application/x-www-form-urlencoded"
+    payload: "mode=off"
+```
+
