+# Sandbox X environment in Docker
+
+This setup creates a VNC server running LXDE with two browsers installed
+(chromium and firefox). 
+The executable connects to the container with SSH. Once SSH session exits,
+the container is destroyed. The executable automatically starts `vncviewer`
+after starting the container if --vnc passed.
+
+Run the `build-run` script to build and run the container.
+Following arguments may be passed:
+
+* `--vnc`        Starts vncviewer
+* `--geometry`   Default geometry for VNC server, e.g. `1024x768`
+* `--new-passwd` Generates a new random `vnc_passwd` file used
+  for authenticating the VNC client.
