 A handwritten msgpack encoder and decoder for Node.JS.
 
+The original format can be found at <http://wiki.msgpack.org/display/MSGPACK/Format+specification>
+
+
+## Extension
+
 I've extended the format a little to allow for encoding and decoding of `undefined` and `Buffer` instances.
 
+This required three new type codes that were previously marked as "reserved".
+This change means that using these new types will render your serialized data
+incompatible with other messagepack implementations that don't have the same
+extension.
+
+There are two new types for storing node `Buffer` instances. These work just 
+like "raw 16" and "raw 32" except they are node buffers instead of strings.
+
+    buffer 16  11011000  0xd8
+    buffer 32  11011001  0xd9
+
+Also I've added a type for `undefined` that works just like the `null` type.
+
+    undefined  11000100  0xc4
+
 ## Usage
 
     var msgpack = require('msgpack');
