121 | noVNC is a browser based VNC client implemented using HTML5 Canvas 122 | and WebSockets. You will either need a VNC server with WebSockets 123 | support (such as libvncserver) 124 | or you will need to use 125 | websockify 126 | to bridge between your browser and VNC server. See the noVNC 127 | README 128 | and website 129 | for more information. 130 |

175 | noVNC is a browser based VNC client implemented using HTML5 Canvas 176 | and WebSockets. You will either need a VNC server with WebSockets 177 | support (such as libvncserver) 178 | or you will need to use 179 | websockify 180 | to bridge between your browser and VNC server.
