+## noVNC: HTML5 VNC Client
+
+
+### Description
+
+noVNC is a VNC client implemented using HTML5 technologies,
+specifically Canvas and WebSockets (supports 'wss://' encryption).
+noVNC is licensed under the
+[LGPLv3](http://www.gnu.org/licenses/lgpl.html).
+
+Special thanks to [Sentry Data Systems](http://www.sentryds.com) for
+sponsoring ongoing development of this project (and for employing me).
+
+There are many companies/projects that have integrated noVNC into
+their products including: [Sentry Data Systems](http://www.sentryds.com), [Ganeti Web Manager](http://code.osuosl.org/projects/ganeti-webmgr), [Archipel](http://archipelproject.org), [openQRM](http://www.openqrm.com/), [OpenNode](http://www.opennodecloud.com/), [OpenStack](http://www.openstack.org), [Broadway (HTML5 GDK/GTK+ backend)](http://blogs.gnome.org/alexl/2011/03/15/gtk-html-backend-update/), [OpenNebula](http://opennebula.org/), [CloudSigma](http://www.cloudsigma.com/), [Zentyal (formerly eBox)](http://www.zentyal.org/), and [SlapOS](http://www.slapos.org). See [this wiki page](https://github.com/kanaka/noVNC/wiki/ProjectsCompanies-using-noVNC) for more info and links.

+
+
+### Browser Requirements
+
+* HTML5 Canvas (with createImageData): Chrome, Firefox 3.6+, iOS
+  Safari, Opera 11+, Internet Explorer 9+, etc.
+
+* HTML5 WebSockets: For browsers that do not have builtin
+  WebSockets support, the project includes
+  <a href="http://github.com/gimite/web-socket-js">web-socket-js</a>,
+  a WebSockets emulator using Adobe Flash. iOS 4.2+ has built-in
+  WebSocket support.
+
+* Fast Javascript Engine: noVNC avoids using new Javascript
+  functionality so it will run on older browsers, but decode and
+  rendering happen in Javascript, so a slow Javascript engine will
+  mean noVNC is painfully slow.
+
+* I maintain a more detailed browser compatibility list <a
+  href="https://github.com/kanaka/noVNC/wiki/Browser-support">here</a>.
+
+
+### Server Requirements
+
+Unless you are using a VNC server with support for WebSockets
+connections (only my [fork of libvncserver](http://github.com/kanaka/libvncserver)
+currently), you need to use a WebSockets to TCP socket proxy. There is
+a python proxy included ('websockify'). One advantage of using the
+proxy is that it has builtin support for SSL/TLS encryption (i.e.
+"wss://").
+
+There a few reasons why a proxy is required:
+
+  1. WebSockets is not a pure socket protocol. There is an initial HTTP
+     like handshake to allow easy hand-off by web servers and allow
+     some origin policy exchange. Also, each WebSockets frame begins
+     with 0 ('\x00') and ends with 255 ('\xff').
+
+  2. Javascript itself does not have the ability to handle pure byte
+     arrays. The python proxy encodes the data as base64 so that the
+     Javascript client can decode the data as an integer array.
+
+
+### Quick Start
+
+* Use the launch script to start a mini-webserver and the WebSockets
+  proxy (websockify). The `--vnc` option is used to specify the location of
+  a running VNC server:
+
+    `./utils/launch.sh --vnc localhost:5901`
+
+* Point your browser to the cut-and-paste URL that is output by the
+  launch script. Enter a password if the VNC server has one
+  configured. Hit the Connect button and enjoy!
