-If you are using Arduino IDE 1.x, place the Messenger folder inside your Documents\Arduino\libraries folder.  Open the DTMF_Shield sketch.
-Use 'upload' to put it onto an Arduino Uno that is plugged in to the computer and recognized.

-I've tested this also with Arduino IDE 2.0.  it works, but there wasn't a Documents\Arduino\libraries folder already existing; I had to make it.  But the compile,
-and the Upload, also worked as well as with the Arduino IDE 1.x.
+Using (currently) the Arduino IDE 2.x, place the libraries/Messenger folder inside your Documents\Arduino\libraries folder.  Place the entire the DTMF_Shield subfolder
+into your Documents\Arduino folder, creating the DTMF_Shield subfolder, containing DTMF_Shield.ino.  Open DTMF_Shield.ino in your Arduino IDE.
+Use 'upload' to put it onto an Arduino Uno that is plugged in to the computer and recognized and selected.
 
 I suspect that this project could be modified to easily program the Kenwood TM-732, and possibly TM-733.  It can also be a generic DTMF generating board.
 The Arduino is just a serial port that accepts commands that are processed by the DTMF_Shield sketch.  DTMF tones and button presses and such result from this.
