+JSON-JRuby
+==========
+
+JSON-JRuby is a port of Florian Frank's native
+[`json` library](http://json.rubyforge.org/) to JRuby.
+It aims to be a perfect drop-in replacement for `json_pure`.
+
+
+Development version
+===================
+
+The latest version is available from the
+[Git repository](http://github.com/mernen/json-jruby/tree):
+
+ git clone git://github.com/mernen/json-jruby.git
+
+
+Compiling
+=========
+
+You'll need JRuby version 1.2 or greater to build JSON-JRuby.
+Its path must be set on the `jruby.dir` property of
+`nbproject/project.properties` (defaults to `../jruby`).
+
+Additionally, you'll need [Ant](http://ant.apache.org/), and
+[Ragel](http://www.cs.queensu.ca/~thurston/ragel/) 6.4 or greater.
+
+Then, from the folder where the sources are located, type:
+
+ ant clean jar
+
+to clean any leftovers from previous builds and generate the `.jar` files.
+To generate a RubyGem, specify the `gem` action rather than `jar`.
