 =head0 Preface
 
-[ be witty here ]
+Perl 6 has had a long gestation period. During that time several
+implementations have been created. These implementations have, in turn,
+informed the design of Perl 6 in ways that wouldn't have been possible
+without developers trying to implement the specification and programmers
+trying to use those implementations to solve real programming problems.
+Because of this interplay between design and implementation, today we
+have more cohesive and consistent language specification and a compiler
+that implements a good bit of it. 
+
+In the pages that follow, you will be introduced to the Perl 6 language
+through its Rakudo implementation. Good luck and as the Perl 6 community
+often says: have fun!
