## noVNC: HTML5 VNC Client
+[![Build Status](https://travis-ci.org/novnc/noVNC.svg?branch=master)](https://travis-ci.org/novnc/noVNC)
### 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).
+noVNC is a HTML5 VNC client that runs well in any modern browser including
+mobile browsers (iOS and Android).
-Special thanks to [Sentry Data Systems](http://www.sentryds.com) for
-sponsoring ongoing development of this project (and for employing me).
+Many companies, projects and products have integrated noVNC including
+[Ganeti Web Manager](http://code.osuosl.org/projects/ganeti-webmgr),
+[OpenStack](http://www.openstack.org),
+[OpenNebula](http://opennebula.org/),
+[LibVNCServer](http://libvncserver.sourceforge.net), and
+[ThinLinc](https://cendio.com/thinlinc). See
+[the Projects and Companies wiki page](https://github.com/novnc/noVNC/wiki/Projects-and-companies-using-noVNC)
+for a more complete list with additional info and links.

### Browser Requirements
-* HTML5 Canvas: Except for Internet Explorer, most
- browsers have had Canvas support for quite some time. Internet
- Explorer 9 will have Canvas support (finally).
+* Chrome 8, Firefox 4, Safari 6, Opera 12, IE 11, Edge 12, 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.
+* HTML5 Canvas, WebSockets and Typed Arrays
-* 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.
+* Fast Javascript Engine: this is not strictly a requirement, but without a
+ fast Javascript engine, noVNC might be painfully slow.
-* I maintain a more detailed list of browser compatibility <a
- href="https://github.com/kanaka/noVNC/wiki/Browser-support">here</a>.
+* See the more detailed
+[browser compatibility wiki page](https://github.com/novnc/noVNC/wiki/Browser-support).
### 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.
+Unless you are using a VNC server with support for WebSockets connections (such
+as [x11vnc/libvncserver](http://libvncserver.sourceforge.net/),
+[QEMU](http://www.qemu.org/), or
+[PocketVNC](http://www.pocketvnc.com/blog/?page_id=866)), you need to use a
+WebSockets to TCP socket proxy. There is a python proxy included
+('websockify').
### 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:

-* 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!
