+What's going on here?
+---------------------
 This is the Wheeler programming language. It is probably different from other languages you've seen. 
 
 There is a REPL that is handy for playing with the language. Just run ./bigwheel
 
-Wheeler doesn't have much implemented yet but you can do some simple things in the REPL such as printing strings and adding numbers. Try it!
+Wheeler doesn't have much implemented yet but you can do some simple things in the REPL such as printing strings or experimenting with transitions (one of the core language features).
 
-There is also an interpreter that you can execute from the commandline like so: ./wheeler
+There is also an interpreter that you can execute from the command line like so: ./wheeler
 
-Wheeler is currently built on top of Python 2.5 and also runs well in 2.6. Python 3 hasn't been tested but may be.
 
+Requirements
+------------
+* Python 2.7
+* the AssociativeTools library https://github.com/built/AssociativeTools
 
+
+How do I run this?
+------------------
+You'll need to have the Associative Tools library in your PYTHONPATH.
+
+After that just type ./bigwheel and you should see the Wheeler prompt.
+
+
+Feedback
+------------------
+I've love your feedback, ideas, and contributions. matt-at-youell-dot-com or @built on twitter.
