  67 ### Browser Requirements
  68
  69 * HTML5 Canvas (with createImageData): Chrome, Firefox 3.6+, iOS
  70   Safari, Opera 11+, Internet Explorer 9+, etc.
  71
  72 * HTML5 WebSockets and Typed Arrays
  73
  74 * Fast Javascript Engine: this is not strictly a requirement, but
  75   without a fast Javascript engine, noVNC might be painfully slow.
  76
  77 * See the more detailed [browser compatibility wiki page](https://github.com/kanaka/noVNC/wiki/Browser-support).
  78
  79
  80 ### Server Requirements
  81
  82 Unless you are using a VNC server with support for WebSockets
  83 connections (such as
  84 [x11vnc/libvncserver](http://libvncserver.sourceforge.net/),
  85 [QEMU](http://www.qemu.org/), or
  86 [PocketVNC](http://www.pocketvnc.com/blog/?page_id=866)), you need to
  87 use a WebSockets to TCP socket proxy. There is a python proxy included
  88 ('websockify').
  89
  90
  91 ### Quick Start
  92
  93 * Use the launch script to start a mini-webserver and the WebSockets
  94   proxy (websockify). The `--vnc` option is used to specify the location of
  95   a running VNC server:
  96
  97     `./utils/launch.sh --vnc localhost:5901`
  98
  99 * Point your browser to the cut-and-paste URL that is output by the
 100   launch script. Enter a password if the VNC server has one
 101   configured. Hit the Connect button and enjoy!
