38### Browser Requirements
39
40* HTML5 Canvas (with createImageData): Chrome, Firefox 3.6+, iOS
41  Safari, Opera 11+, Internet Explorer 9+, etc.
42
43* HTML5 WebSockets: For browsers that do not have builtin
44  WebSockets support, the project includes
45  <a href="http://github.com/gimite/web-socket-js">web-socket-js</a>,
46  a WebSockets emulator using Adobe Flash. iOS 4.2+ has built-in
47  WebSocket support.
48
49* Fast Javascript Engine: this is not strictly a requirement, but
50  without a fast Javascript engine, noVNC might be painfully slow.

52* I maintain a more detailed browser compatibility list <a

56### Server Requirements
57
58Unless you are using a VNC server with support for WebSockets
59connections (such as [x11vnc/libvncserver](http://libvncserver.sourceforge.net/)),
60you need to use a WebSockets to TCP socket proxy. There is
61a python proxy included ('websockify').
62
63
64### Quick Start
65
66* Use the launch script to start a mini-webserver and the WebSockets
67  proxy (websockify). The `--vnc` option is used to specify the location of
68  a running VNC server:
69
70    `./utils/launch.sh --vnc localhost:5901`
71
72* Point your browser to the cut-and-paste URL that is output by the
73  launch script. Enter a password if the VNC server has one
74  configured. Hit the Connect button and enjoy!
