+### Obtaining an app configuration
+
+If there is an app you want to be able to launch from Home Assistant that isn't detected by default, you will need to specify the app configuration in `configuration.yaml`. In order to determine the values to specify for each configuration parameter, launch the app you want to configure on your device, and run the following command (requires `pyvizio` to be installed locally):
+
+```bash
+pyvizio --ip={IP:PORT} get-current-app-config
+```
+
+`pyvizio` will return the value of the three parameters (`APP_ID`, `NAME_SPACE`, `MESSAGE`) for the currently running app which you can then include in your configuration.
+
+### Obtaining a list of valid apps to include or exclude
+To get the list of apps that can be excluded or included, run the following command (requires `pyvizio` to be installed locally):
+
+```bash
+pyvizio --ip=0 get-apps-list
+```
