 INSTALLATION
 Detailed instructions are in reference/Guide_Windows.html and
 reference/Guide_MacOSX.html.  For Linux, see the Arduino playground:
 http://www.arduino.cc/playground/Learning/Linux
 
-If you are using a USB Arduino, you will need to install the drivers for the
-FTDI chip on the board. These can be found in the drivers/ directory.
-
-* On Windows, plug in the Arduino board and point the Windows Add Hardware
-  wizard to the drivers/FTDI USB Drivers sub-directory of the Arduino
-  application directory.
-
-* On the Mac, install the FTDIUSBSerialDriver_10_4_10_5_10_6.mpkg package.
-  
-* On Linux, drivers are included in kernel versions 2.4.20 or greater.
