+# Xubuntu on Docker
+
+A Docker image based on Ubuntu 18.04 with Xfce desktop environment,
+[VirtualGL](https://github.com/VirtualGL/virtualgl),
+[XRDP](https://github.com/neutrinolabs/xrdp) and
+[XRDP PulseAudio module](https://github.com/neutrinolabs/pulseaudio-module-xrdp).
+
+## Start an instance
+
+```sh
+docker run --detach \
+  --name xubuntu \
+  --publish 3389:3389/tcp \
+  hectormolinero/xubuntu:latest
+```
+
+> You will be able to connect to the container via RDP through 3389/tcp port.
+
+> **Important:** if you use the `--privileged` option the container will be able to use the GPU with
+VirtualGL, but this will conflict with the host X server.
+
+> **Important:** some software (like Firefox) need the shared memory to be increased, if you
+encounter any problem related to this you may use the `--shm-size` option.
+
+## Environment variables
+
+* `GUEST_USER_PASSWORD`: guest user password (`guest` by default).
