 ## Testing and usage
 
-To test your installation, you can download one of the example LoRa signals at [rpp0/gr-lora-samples](https://github.com/rpp0/gr-lora-samples). Configure ```apps/lora_receive_file.py``` to use the sample and run the script. You should see the decoded sample data:
+To test your installation, you can simply run the example app ```apps/lora_receive_file_nogui.py```. The script will download an example trace, and attempt to decode it using gr-lora. You should see the following output:
 
 ```
-$ ./lora_receive_file.py

-Alternatively, if you have a hardware LoRa transmitter, you use ```apps/lora_receive_realtime.py``` to decode signals in real time. If you have a Microchip RN2483, you can use [python-loranode](https://github.com/rpp0/python-loranode) to easily send messages via Python.
+Other example traces can be found [in the gr-lora-samples repository](https://github.com/rpp0/gr-lora-samples).

 By default, decoded messages will be printed to the console output. However, you can use a `message_socket_sink` to forward messages to port 40868 over UDP. See the [tutorial](https://github.com/rpp0/gr-lora/wiki/Capturing-LoRa-signals-using-an-RTL-SDR-device) for more information.
