  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.
  51
  52 * I maintain a more detailed browser compatibility list <a

  56 ### Server Requirements
  57
  58 Unless you are using a VNC server with support for WebSockets
  59 connections (such as [x11vnc/libvncserver](http://libvncserver.sourceforge.net/)),
  60 you need to use a WebSockets to TCP socket proxy. There is
  61 a 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!
