 = Yapsi -- Yet Another Perl Six Implementation
 
-This is an implementation of a Perl 6 compiler-and-runtime in Perl 6. It
-currently runs off the old, pre-refactor branch of Rakudo known as 'alpha'.
-You need to have an old version of Rakudo installed (say, the 2010-01
-release), and available in your path under the name 'alpha'.
+This is an implementation of a Perl 6 compiler-and-runtime in Perl 6.
 
 == Building Yapsi
 
-This assumes that you have a working installation of alpha somewhere in
-your $PATH. Yapsi currently works on top of alpha, an older branch of rakudo.
-If you have not built alpha yet, please build it by doing a git clone from 
-<git://github.com/rakudo/rakudo.git> and "git checkout origin/alpha".
-
-To build Yapsi:
-    * type make in the directory where you've cloned Yapsi.
-    * copy the generated lib/Yapsi.pir to $PERL6LIB or ~/.perl6/lib folder.

+$ ufo && make
