+
+## Build the Container
+
+This command builds the Docker image from the `Dockerfile` in the current directory.
+The `-t novnc` option tags the image with the name `novnc`.
 
-### Stand-alone Demo
-Run:
 ```bash
-$ docker run --rm -it -p 8080:8080 theasp/novnc
+docker build -t novnc .
 ```
-Open a browser and see the `xterm` demo at `http://<server>:8080/vnc.html`
 
-### V2 Composition
-A version of the [V2 docker-compose example](https://github.com/theasp/docker/blob/master/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.
+## Run the Container
 
-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
+This command starts a container from the `novnc` image.
 
+```bash
+docker run -p 8080:8080 novnc
 ```

+### Autostart Firefox Example
+
+This command starts a container from the `novnc` image and automatically starts Firefox.
+
+```bash
+docker run -p 8080:8080 -e RUN_FIREFOX=True novnc
 ```
-**If the IDE fails to start simply run `docker-compose restart <container-name>`.**
