+#Complete Spice Web Client written in HTML5 and Javascript 
+Full and complete implementation of the SPICE protocol (by Red Hat) written in HTML5 and JavaScript. It allows any standard HTML5-ready Web Browser to connect to remote 
+virtual sessions just by accessing a single URL.
+
+The client can be deployed through a normal web server to connect to spice sessions. To use it you would need to proxy your spice session through a websockets-to-tcp 
+proxy like Kanaka, Websockify or similar projects.
+
+NOTE: This project is NOT based on the spice-html5 prototype.
+
+## Features
+
+- Full QXL Support of the entire spice protocol, including clipping, masking, scaling etc (accelerated mode)
+- Audio support, but only for raw audio samples, not for celt
+- Full KeyBoard support including English, Spanish and Catalan layouts
+- Clipboard sharing support with customizble interface
+- Video streaming support with excellent performance even at 60fps FHD 1080p
+- Extremly high performant LZ decoder with sub <10ms for a FHD 1080P image
+- Pure Javascript codec for quic
+- Configurable multi core support using webworkers (by default it uses 4 CPU Cores)
+- Spice Agent support
+- Set resolution support
+- Honors spice cache for images, cursors and palettes
+- Very low memory footprint for a javascript application like this
+- Spice authentication tokens support
+- Supports graphic live debugging the spice protocol and to replay packets to fix bugs
+
+##Missing features
+
+There are some SPICE features still to be implemented, the most important ones are:
+
+- Celt or other audio codec
+- USB redirection (not possible at browser level, maybe with a plugin?)
+
+##Client System requirements
+
+To get the best result we recommend at least 1GB of ram and at least two cores at 1,5ghz. 
+
+It should work decently on 512mb of ram and 1ghz.
+
+We have made tests in raspberry pi 2 with very good results.
+
+##Network requirements
+
+Only Binary websockets are used to send and receive server data, so you should expect similar network requirements than SPICE itself.
+for a normal 1080p session the performance is very good up to 150-200ms of latency and 100kb/s bandwidth.
+
+The network consumption of a spice session depends a lot on the usage patterns.    
+
+##Performance
+
+Writing a web client for a protocol like spice is challenge because of the limited access to system resources like GPU and the way the javascript VM works.
+
+We have spent almost 2 years profiling the entire project. The lz decoder has been optimized to <10Ms for full hd images. Quic codec has been hacked a lot 
+to get acceptable performance even being executed in javascript.
+
+We have created a graphic pipeline to remove unnecesary draw operations that are going to be overdrawn at the next known packets. We have minimized the work
+for the javascript GC and refined all our canvas operations and all the entire stack to prevent big data structures to be copied.
+
+You should expect a near perfect experience if you meet the client requirements and the network requirements.
+
+##Browser support
+
+We strongly recommend use the spice web client with Chromium/Chrome or Firefox, however it should work at least on:
+
+- Google Chrome
+- Firefox
+- Internet Explorer 11
+- Edge
+
+
+##How to use it
+
+In order to work you only need to provide the IP address of the websockets proxy and the port
+of the websockets proxy.
+
+You can do it permanently editing run.js or through the URL using the parameters:
+
+http://example.com/spice-web-client/index.html?host=IP_ADDRESS_OF_WEBSOCKIFY&port=TCP_PORT_OF_WEBSOCKIFY
+
+By doing this you will connect to the remote spice session and the resolution will be adapted to your browser viewport area.
+
+##Notes For linux sessions
+If you are planning to use this to connect to remote linux sessions you should consider disabling compositing on your desktop. The best performance is achieved with
+kde with compositing and visual effects disabled.
+
+Always install the spice-vdagent and xorg-qxl to get the best results and to have custom resolutions etc.
+
+##Notes For Windows sessions
+
+Spice web client has a very good performance connecting to remote windows sessions. Always install the spice-agent package including the qxl video driver to get the best results and to have custom resolutions etc.
