 Test First Ruby -- RSpec 3 Edition
 ==========
+# Chris Reed
 
 See [testfirst.org/learn_ruby](http://testfirst.org/learn_ruby#install) for more information about how this will work.  These test-first Ruby challenges have been forked from [https://github.com/alexch/learn_ruby](https://github.com/alexch/learn_ruby) and updated to use RSpec 3 instead of RSpec 2.
