 #### For Windows Users:
 ```
-runas /user:Administrator "cmd /c python3 arduino_exec.py --port COM3 2>&1"
+runas /user:Administrator "cmd /c python3 arduino_exec.py -p COM3"
 ```
 
 Note that if you don't plan on executing any commands that require the extra administrative permissons you can run the program directly just using Python alone without including the `runas /user:Administrator` prefix. Some of the sketches in the public gallery require administrative permissions, specifically those that allow the Arduino to shut down, reboot, or put the host machine to sleep:
 
 ```
-python3 arduino_exec.py --port COM3 2>&1
+python3 arduino_exec.py -p COM3
 ```
 
 #### For Mac and Linux Users:
-Replace the device path '/dev/cu.usbserial-A4016Z9Q' with the path to your Arduino port.
+Replace the device path '/dev/cu.usbserial-00100' with the path to your Arduino port.

-The `2>&1` term will ensure that all output is captured and returned to your Arduino including any output directed to `stderr` in addition to the normal output sent to `stdout`.
