+Works only with the standalone app and the external prompter, not the in-frame one. Windows only, sorry.
 Make sure the you have the "Footswitch_Arduino.ino" sketch loaded onto the Arduino and the footswitch connected between pin 4 and GND. I am using the foot pedal from my keyboard.
+The script "footswitch_cmd.py" is written for Python 3 and needs pyserial and pywinauto to be installed. Adjust the COM-Port in the script to your system. 
 
 ## Operation:
-- Run this script.
-- Load your script in the Imaginary Teleprompter and start the external prompter by clicking "Prompt It!".
-- Pause the prompter with the space key.
+- Run footswitch_cmd.py and watch the output: It should say "Footswitch connected". Otherwise check the serial port in the script.
+- Load your text in Imaginary Teleprompter and start the external prompter by clicking "Prompt It!".
+- Pause the prompter with the space key on your keyboard.
 - A short press of the footswitch sends "Page Down" to the teleprompter, scrolling half a page down.
 - A long press (>300ms) starts the automatic scrolling as long as the footswitch is depressed (and stops it when released).
