+# Arduino Makefile
+# Arduino adaptation by mellis, eighthave, oli.keller
+#
+# This makefile allows you to build sketches from the command line
+# without the Arduino environment (or Java).
+#
+# Detailed instructions for using the makefile:
+#
+#  1. Copy this file into the folder with your sketch. There should be a
+#     file with the same name as the folder and with the extension .pde
+#     (e.g. foo.pde in the foo/ folder).
+#
+#  2. Modify the line containg "INSTALL_DIR" to point to the directory that
+#     contains the Arduino installation (for example, under Mac OS X, this
+#     might be /Applications/arduino-0012).
+#
+#  3. Modify the line containing "PORT" to refer to the filename
+#     representing the USB or serial connection to your Arduino board
+#     (e.g. PORT = /dev/tty.USB0).  If the exact name of this file
+#     changes, you can use * as a wildcard (e.g. PORT = /dev/tty.usb*).
+#
+#  4. Set the line containing "MCU" to match your board's processor. 
+#     Older one's are atmega8 based, newer ones like Arduino Mini, Bluetooth
+#     or Diecimila have the atmega168.  If you're using a LilyPad Arduino,
+#     change F_CPU to 8000000.
+#
+#  5. At the command line, change to the directory containing your
+#     program's file and the makefile.
+#
+#  6. Type "make" and press enter to compile/verify your program.
+#
+#  7. Type "make upload", reset your Arduino board, and press enter to
+#     upload your program to the Arduino board.
