+## Developing
+
+While I know it's somewhat discriminatory in the PHP world since many of
+you are still on windows (thus making working with ruby a bit more difficult), 
+I've created a rakefile that takes care of common tasks (such as generating docs, 
+building release tarballs, etc.)  This probably isn't relevant to anything you 
+would be doing unless you want to fork this project and release your version of it.
+
+On that note, if you'd like to contribute to the project, you can either fork it and
+submit back to me, or you can ask to be a contributor.  Reach out to me if you're 
+interested, I'm happy to chat :)
