+Until March 2012, this was simply posted on my website where you can still find
+[what documentation][docs] exists.
 
 If you're using Debian or Ubuntu, you can find this in the arduino-core package.
+
+This Makefile current requires either Arduino 1.0 or MPIDE 0023.
+
+## chipKIT Support
+
+In addition to regular Arduino boards, this Makefile supports the Digilent
+chipKIT Uno32 and Max32, both Arduino-compatible microcontrollers. To use this
+Makefile with one of those, include `chipKIT.mk` instead of `Arduino.mk` at the
+bottom of your Makefile.
+
+    include /path/to/chipKIT.mk
+
+You can adjust the same variables [as described for the Arduino][docs], but the
+`ARDUINO_DIR` variable must point to an MPIDE installation (which includes the
+chipKIT toolchain) instead of the Arduino IDE.
+
+
+Some details on the addition of chipKIT support can be found in another
+[blog post](http://christopherpeplin.com/2011/12/chipkit-arduino-makefile/).
