+Example Project
+
+This example project gives an example of some passing, ignored, and failing tests.
+It's simple and meant for you to look over and get an idea for what all of this stuff does.
+
+You can build and test using the makefile if you have gcc installed (you may need to tweak
+the locations of some tools in the makefile).  Otherwise, the rake version will let you
+test with gcc or a couple versions of IAR.  You can tweak the yaml files to get those versions
+running.
+
+Ruby is required if you're using the rake version (obviously).  This version shows off most of
+Unity's advanced features (automatically creating test runners, fancy summaries, etc.)  
+
+The makefile version doesn't require anything outside of your normal build tools, but won't do the
+extras for you.  So that you can test right away, we've written the test runners for you and 
+put them in the test\no_ruby subdirectory.  If you make changes to the tests or source, you might
+need to update these (like when you add or remove tests).  Do that for a while and you'll learn
+why you really want to start using the Ruby tools.
