-# Kernel Gateway Stack
-
-## What it Gives You
-
-* [Jupyter Kernel Gateway](https://github.com/jupyter-incubator/kernel_gateway) that enables programmatic access to kernels
-* Python 3 kernel
-* No preinstalled scientific computing packages
-* [tini](https://github.com/krallin/tini) as the container entrypoint
-
-## Basic Use
-
-The following command starts a container with the Kernel Gateway server listening for HTTP connections on port 8888.
-
-```
-docker run -d -p 8888:8888 jupyter/minimal-kernel
-```
