+This component can be used as a simple chatbot as well.
+
+You can provide a list of messages to queue and they will be automatically displayed one after the other.
+There is a wait time between each message so that the user can properly read them.
+This wait time is calculated from the length of the last message, and can be configured using the `messages.messageQueueWPM` key in `config.ts`.
+
+You can queue messages like so:
+
+```
+{
+    "key": "queueMessages",
+    "data":
+    {
+        "messages":
+        [
+            {
+                "originator": ...
+                "message": ...
+            },
+            {
+                "originator": ...
+                "message": ...
+            },
+            ...
+        ]
+    }
+}
+```

 You can use the `MessageSender` class to send messages from the TFW server or event handlers written in Python.
