 Supported Platforms
 -------------------
 
-Celluloid works on Ruby 1.9.3, JRuby 1.6 (in 1.9 mode), and Rubinius 2.0. JRuby
-or Rubinius are the preferred platforms as they support true hardware-level
-parallelism for Ruby threads, whereas MRI/YARV is constrained by a global
-interpreter lock (GIL) and can only execute one thread at a time.

-To use JRuby in 1.9 mode, you'll need to pass the "--1.9" command line option
-to the JRuby executable, or set the "JRUBY_OPTS=--1.9" environment variable.
+Celluloid requires Ruby 1.9 mode on all interpreters. This works out of the
+box on MRI/YARV, and requires the following flags elsewhere:
 
-Celluloid works on Rubinius in either 1.8 or 1.9 mode.
+* JRuby: --1.9 command line option, or JRUBY_OPTS=--1.9 environment variable
+* rbx: -X19 command line option
