+# Alpine X11 Display Container
+```
+```
+This image is intended to be used for displaying X11 applications from other containers in a browser. A stand-alone demo as well as a [Version 2](https://docs.docker.com/compose/compose-file/#version-2) composition. Thanks to [Alpine](https://hub.docker.com/_/alpine/), this image is < 100Mb and eliminates the need to run an X11 server on your host machine.
+## Image Contents
+___
+* [Xvfb](http://www.x.org/releases/X11R7.6/doc/man/man1/Xvfb.1.xhtml) - X11 in a virtual framebuffer
+* [x11vnc](http://www.karlrunge.com/x11vnc/) - A VNC server that scrapes the above X11 server
+* [noNVC](https://kanaka.github.io/noVNC/) - A HTML5 canvas vnc viewer
+* [Fluxbox](http://www.fluxbox.org/) - a small window manager
+* [socat](http://www.dest-unreach.org/socat/) - for use with other containers
+* [xterm](http://invisible-island.net/xterm/) - to demo that it works
+* [supervisord](http://supervisord.org) - to keep it all running
+## Usage
+___
+### Stand-alone Demo
+*On Windows and OS X Only -*
+Determine the Docker machine IP address:
+```bash
+$ docker-machine ip $(docker-machine active)
+192.168.99.101
+```
+Run: 
+```bash
+$ docker run --rm -it -p 8080:8080 psharkey/novnc
+```
+Open a browser and hit the *Connect* button to see the `xterm` demo at `http://<DOCKER_MACHINE_IP>:8080/vnc.html`
+### V2 Composition
+A version of the [V2 docker-compose example](https://github.com/psharkey/docker/blob/master/novnc/docker-compose.yml) is shown below to illustrate how this image can be used to greatly simplify the use of X11 applications in other containers. With just `docker-compose up -d`, your favorite IDE can be accessed via a browser.
+
+Some notable features:
+* An `x11` network is defined to link the IDE and novnc containers
+* The IDE `DISPLAY` environment variable is set using the novnc container name
+* The screen size is adjustable to suit your preferences via environment variables
+* The only exposed port is for HTTP browser connections

+**If the IDE fails to start simply run `docker-compose restart <container-name>`.**
