+This is an example C++ library for Arduino 0004+, based on one created by 
+Nicholas Zambetti for Wiring 0006+
+
+Installation
+--------------------------------------------------------------------------------
+
+To install this library, just place this entire folder as a subfolder in your
+Arduino/lib/targets/libraries folder.
+
+When installed, this library should look like:
+
+Arduino/lib/targets/libraries/Test              (this library's folder)
+Arduino/lib/targets/libraries/Test/Test.cpp     (the library implementation file)
+Arduino/lib/targets/libraries/Test/Test.h       (the library description file)
+Arduino/lib/targets/libraries/Test/keywords.txt (the syntax coloring file)
+Arduino/lib/targets/libraries/Test/examples     (the examples in the "open" menu)
+Arduino/lib/targets/libraries/Test/readme.txt   (this file)
+
+Building
+--------------------------------------------------------------------------------
+
+After this library is installed, you just have to start the Arduino application.
+You may see a few warning messages as it's built.
+
+To use this library in a sketch, go to the Sketch | Import Library menu and
+select Test.  This will add a corresponding line to the top of your sketch:
+#include <Test.h>
+
+To stop using this library, delete that line from your sketch.
+
+Geeky information:
+After a successful build of this library, a new file named "Test.o" will appear
+in "Arduino/lib/targets/libraries/Test". This file is the built/compiled library
+code.
+
+If you choose to modify the code for this library (i.e. "Test.cpp" or "Test.h"),
+then you must first 'unbuild' this library by deleting the "Test.o" file. The
+new "Test.o" with your code will appear after the next press of "verify"
+
