 *Note: The device model identifier must be globally unique, and device instance identifier must be unique within the Google Developer Project associated with the device.*
 
 - Run the push to talk sample. The sample records a voice query after a key press and plays back the Google Assistant's answer::
 
-    python -m pushtotalk --device-id 'my-device-identifier'
+    python -m pushtotalk --device-id 'my-device-identifier' --device-model-id 'my-model-identifier'
 
 - Try some Google Assistant voice query like "What time is it?" or "Who am I?".
 
 - Try a device action query like "Turn <nickname / model product name> on".
 
 - Run in verbose mode to see the gRPC communication with the Google Assistant API::
 
-    python -m pushtotalk --device-id 'my-device-identifier' -v
+    python -m pushtotalk --device-id 'my-device-identifier' --device-model-id 'my-model-identifier' -v
 
 - Send a pre-recorded request to the Assistant::
 
-    python -m pushtotalk --device-id 'my-device-identifier' -i in.wav
+    python -m pushtotalk --device-id 'my-device-identifier' --device-model-id 'my-model-identifier' -i in.wav
 
 - Save the Assistant response to a file::
 
-    python -m pushtotalk --device-id 'my-device-identifier' -o out.wav
+    python -m pushtotalk --device-id 'my-device-identifier' --device-model-id 'my-model-identifier' -o out.wav
+
+- Send text requests to the Assistant::
+
+    python -m textinput --device-id 'my-device-identifier' --device-model-id 'my-model-identifier'
