 ### Python Demos
 
-To run the Python demo, run the following in the console:
+Install the demo package:
 
 ```console
 pip3 install pvorcademo
 ```
 
+Run the streaming demo:
+
 ```console
-orca_demo_streaming --access_key ${ACCESS_KEY} --text-to-stream ${TEXT}
+orca_demo_streaming --access_key ${ACCESS_KEY} --text_to_stream ${TEXT}
 ```
 
+Run the single synthesis demo:
+
 ```console
 orca_demo --access_key ${ACCESS_KEY} --text ${TEXT} --output_path ${WAV_OUTPUT_PATH}
 ```
 
 Replace `${ACCESS_KEY}` with yours obtained from Picovoice Console, `${TEXT}` with the text to be synthesized, and
 `${WAV_OUTPUT_PATH}` with a path to an output WAV file.
