+### Disabling the piano switch function

+- Move all of the switches to the off (up) position.
+- As `sudo`, open the `/etc/xdg/lxsession/LXDE-pi` file.  One way to do this is to open __Terminal__, then run this command: `sudo leafpad /etc/xdg/lxsession/LXDE-pi`.  __Leafpad__ is like __Notepad__ in Windows.
+- Locate the line: `@bash /usr/local/bin/check-piano.sh`
+- Insert `#` at the beginning of that line, so that the file looks like this:

+		@pcmanfm --desktop --profile LXDE-pi
