### Browser Requirements
-* Chrome 49, Firefox 44, Safari 10, Opera 36, IE 11, Edge 12, etc.
-
-* HTML5 Canvas, WebSockets and Typed Arrays, etc.
+noVNC uses many modern web technologies so a formal requirement list is
+not available. However these are the minimum versions we are currently
+aware of:
-* Fast Javascript Engine: this is not strictly a requirement, but without a
- fast Javascript engine, noVNC might be painfully slow.
-
-* See the more detailed
-[browser compatibility wiki page](https://github.com/novnc/noVNC/wiki/Browser-support).
+* Chrome 49, Firefox 44, Safari 11, Opera 36, IE 11, Edge 12
### Server Requirements
-Unless you are using a VNC server with support for WebSockets connections (such
-as [x11vnc/libvncserver](http://libvncserver.sourceforge.net/),
-[QEMU](http://www.qemu.org/), or
-[MobileVNC](http://www.smartlab.at/mobilevnc/)), you need to use a
-WebSockets to TCP socket proxy. There is a python proxy included
-('websockify').
+noVNC follows the standard VNC protocol, but unlike other VNC clients it does
+require WebSockets support. Many servers include support (e.g.
+[x11vnc/libvncserver](http://libvncserver.sourceforge.net/),
+[QEMU](http://www.qemu.org/), and
+[MobileVNC](http://www.smartlab.at/mobilevnc/)), but for the others you need to
+use a WebSockets to TCP socket proxy. noVNC has a sister project
+[websockify](https://github.com/novnc/websockify) that provides a simple such
+proxy.
### Quick Start
-* Use the launch script to start a mini-webserver and the WebSockets proxy
- (websockify). The `--vnc` option is used to specify the location of a running
- VNC server:
+* Use the launch script to automatically download and start websockify, which
+ includes a mini-webserver and the WebSockets proxy. The `--vnc` option is
+ used to specify the location of a running VNC server:
`./utils/launch.sh --vnc localhost:5901`
* Point your browser to the cut-and-paste URL that is output by the launch
- script. Enter a password if the VNC server has one configured. Hit the
- Connect button and enjoy!
+ script. Hit the Connect button, enter a password if the VNC server has one
+ configured, and enjoy!
+
+### Installation from Snap Package
+Running the command below will install the latest release of noVNC from Snap:
+
+`sudo snap install novnc`
+
+#### Running noVNC
+
+You can run the Snap-package installed novnc directly with, for example:
+
+`novnc --listen 6081 --vnc localhost:5901 # /snap/bin/novnc if /snap/bin is not in your PATH`
+#### Running as a Service (Daemon)
+The Snap package also has the capability to run a 'novnc' service which can be
+configured to listen on multiple ports connecting to multiple VNC servers
+(effectively a service runing multiple instances of novnc).
+Instructions (with example values):
-### Other Pages
+List current services (out-of-box this will be blank):
-* [Modules/API](https://github.com/novnc/noVNC/blob/master/docs/API.md) - The library
- modules and their Javascript API.
+```
+sudo snap get novnc services
+Key Value
+services.n6080 {...}
+services.n6081 {...}
+```
-* [Integration](https://github.com/novnc/noVNC/wiki/Integration) - Get noVNC
- to work in existing projects.
+Create a new service that listens on port 6082 and connects to the VNC server
+running on port 5902 on localhost:
-* [Troubleshooting](https://github.com/novnc/noVNC/wiki/Troubleshooting) - How
- to troubleshoot problems.
+`sudo snap set novnc services.n6082.listen=6082 services.n6082.vnc=localhost:5902`
-* [Encrypted Connections](https://github.com/novnc/websockify/wiki/Encrypted-Connections) -
- Setup websockify so that you can use encrypted connections from noVNC.
+(Any services you define with 'snap set' will be automatically started)
+Note that the name of the service, 'n6082' in this example, can be anything
+as long as it doesn't start with a number or contain spaces/special characters.
-* [Advanced Usage](https://github.com/novnc/noVNC/wiki/Advanced-usage) -
- Generating an SSL certificate, starting a VNC server, advanced websockify
- usage, etc.
+View the configuration of the service just created:
-* [Testing](https://github.com/novnc/noVNC/wiki/Testing) - Run and write
- tests.
+```
+sudo snap get novnc services.n6082
+Key Value
+services.n6082.listen 6082
+services.n6082.vnc localhost:5902
+```
-* [Translations](https://github.com/novnc/noVNC/wiki/Translations) - Add and
- modify localization for JavaScript and HTML.
+Disable a service (note that because of a limitation in Snap it's currently not
+possible to unset config variables, setting them to blank values is the way
+to disable a service):
+
+`sudo snap set novnc services.n6082.listen='' services.n6082.vnc=''`
+
+(Any services you set to blank with 'snap set' like this will be automatically stopped)
+
+Verify that the service is disabled (blank values):
+
+```
+sudo snap get novnc services.n6082
+Key Value
+services.n6082.listen
+services.n6082.vnc
+```
+
+### Integration and Deployment
+
+Please see our other documents for how to integrate noVNC in your own software,
+or deploying the noVNC application in production environments:
+
+* [Embedding](docs/EMBEDDING.md) - For the noVNC application
+* [Library](docs/LIBRARY.md) - For the noVNC JavaScript library
