+MessagePack-RPC
+===============
+
+## Overview
+
+MessagePack-RPC is an inter-process messaging library that uses [MessagePack](http://msgpack.sourceforge.net/) for object serialization.
+
+MessagePack enables very fast streaming serialization/deserialization, and communication between heterogeneous languages like Ruby <-> C++.
+
+  - Asynchronous, synchronous and callback interfaces are supported.
+  - Scalable event-driven architecture.
+  - Deflate compression is supported.
+
+
+## Status
+
+Currently, MessagePack-RPC supports only Ruby. MessagePack-RPC for Ruby is available by RubyGems:
+
+    $ gem install msgpack-rpc
