      5 ### Description
      6 
      7 noVNC is a HTML5 VNC client that runs well in any modern browser
      8 including mobile browsers (iPhone/iPad and Android).
      9 
     10 Many companies/projects have integrated noVNC including [Ganeti Web
     11 Manager](http://code.osuosl.org/projects/ganeti-webmgr),
     12 [OpenStack](http://www.openstack.org),
     13 [OpenNebula](http://opennebula.org/), and
     14 [LibVNCServer](http://libvncserver.sourceforge.net). See [the Projects
     15 and Companies wiki
     16 page](https://github.com/kanaka/noVNC/wiki/ProjectsCompanies-using-noVNC)

     65 
     66 
     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: For browsers that do not have builtin
     73   WebSockets support, the project includes
     74   <a href="http://github.com/gimite/web-socket-js">web-socket-js</a>,
     75   a WebSockets emulator using Adobe Flash. iOS 4.2+ has built-in
     76   WebSocket support.
     77 
     78 * Fast Javascript Engine: this is not strictly a requirement, but
     79   without a fast Javascript engine, noVNC might be painfully slow.
     80 
     81 * See the more detailed [browser compatibility wiki page](https://github.com/kanaka/noVNC/wiki/Browser-support).
     82 
     83 
     84 ### Server Requirements
     85 
     86 Unless you are using a VNC server with support for WebSockets
     87 connections (such as
     88 [x11vnc/libvncserver](http://libvncserver.sourceforge.net/),
     89 [QEMU](http://www.qemu.org/), or
     90 [PocketVNC](http://www.pocketvnc.com/blog/?page_id=866)), you need to
     91 use a WebSockets to TCP socket proxy. There is a python proxy included
     92 ('websockify').
     93 
     94 
     95 ### Quick Start
     96 
     97 * Use the launch script to start a mini-webserver and the WebSockets
     98   proxy (websockify). The `--vnc` option is used to specify the location of
     99   a running VNC server:
    100 
    101     `./utils/launch.sh --vnc localhost:5901`
    102 
    103 * Point your browser to the cut-and-paste URL that is output by the
    104   launch script. Enter a password if the VNC server has one
    105   configured. Hit the Connect button and enjoy!
