+Development notes
+--------------------------------------------------------------------------------
+It is worth noting that some of the tests will fail when ran against nginx,
+which is the default web server for some local development systems. As a result,
+it is recommended to run tests on a server that uses Apache HTTPd Server instead
+of nginx.
