+In this other example, you can see the property "play" in action. This property allow you to replay the last previously stored message.<br/>
+This allow to save the state of a node and then replay it back whenever you want.

 	<p>The meaning of this node is to interrupt/reactivate flow messages.<br/>
-	<p>The node will stop output messages, if it receives a payload = false from the specified topic.<br/>
-	The node will resume output messages, if it receives a payload = true from the specified topic.<br/>
+	Normally, passes the input messages to the output. If you send a payload with a specific topic (you can set it on the node properties), the node stops sending output messages.<br/>
+	It can also save the last message received and play later. This is useful if you wish to restore previous state to, for example, a light actuator.<br/>
+	Please see the <a href="https://github.com/Supergiovane/node-red-contrib-boolean-logic-ultimate" target="_blank">README</a> on github for examples.
