+# The default user image
+
+This Docker image is the Helm chart's default user image. It contains the
+fundamentals only so that it can get pulled quickly. It is based on the
+[base-notebook image](https://github.com/jupyter/docker-stacks/blob/HEAD/base-notebook/Dockerfile)
+from Project Jupyter's [jupyter/docker-stacks repository](https://github.com/jupyter/docker-stacks)
+which also contains many other images suitable for use with the Helm chart. To
+help you choose another one see [the docker-stacks documentation on selecting a
+user image](http://jupyter-docker-stacks.readthedocs.io/en/latest/using/selecting.html).
+
+For a brief introduction to _Dockerfiles_, _images_ and _containers_, see [the
+guide's summary about container technology.](https://z2jh.jupyter.org/en/latest/tools.html#container-technology).
+
+## Basic usage
+
+To quickly try out this Docker image on your computer:
+
+```sh
+# with the classic UI
+docker run  -it  --rm  -p 8888:8888 codechina/k8s-singleuser-sample
+
+# with JupyterLab
+docker run  -it  --rm  -p 8888:8888 -e JUPYTER_ENABLE_LAB=true codechina/k8s-singleuser-sample
+```
+
+This image available tags can be found [here](https://hub.docker.com/r/codechina/k8s-singleuser-sample/tags/).
+
+## In the base-notebook image
+
+- Ubuntu Linux - v18.04 aka. Bionic
+- JupyterHub - required by with Helm chart since KubeSpawner requires it
+- [JupyterLab](https://jupyterlab.readthedocs.io/en/stable/) and [JupyterLab-Hub extension](https://jupyterlab.readthedocs.io/en/stable/user/jupyterhub.html) - to activate it over the classical UI by default, see [the guide's instructions](https://z2jh.jupyter.org/en/latest/user-environment.html#use-jupyterlab-by-default).
