 Hey hackers,
 
-cdist has not been published, you're accessing a early in developent
-code.
+this README is for you, for those who want to dig into cdist, hack it or try
+to get a deeper understanding.
 
-Do not believe anything written in cdist, besides what's written in this file
-(everything else may be future stuff for the initial release).
+A lot of documentation is still missing, but running cdist-quickstart should
+give you an impression of how cdist works.
 
-   -- Nico, 20101201
+I hope you have a lot of fun with cdist, because it was also a lot of fun to
+develop it!
