+# RFC6455 - The WebSocket Protocol
+
+[![Build Status](https://travis-ci.org/ratchetphp/RFC6455.svg?branch=master)](https://travis-ci.org/ratchetphp/RFC6455)
+![Autobahn Testsuite](https://img.shields.io/badge/Autobahn-passing-brightgreen.svg)
+
+This library a protocol handler for the RFC6455 specification.
+It contains components for both server and client side handshake and messaging protocol negotation.
+
+Aspects that are left open to interpertation in the specification are also left open in this library.
+It is up to the implementation to determine how those interpertations are to be dealt with.
+
+This library is independent, framework agnostic, and does not deal with any I/O.
+HTTP upgrade negotiation integration points are handled with PSR-7 interfaces.
