-## What is Dockerfile.alpine
-
-Dockerfile.alpine contains the base image for jupyterhub. It does not work independently, but only as part of a full jupyterhub cluster
-
-## How to use it?
-
-You will need:
-
-1. A running configurable-http-proxy, whose API is accessible.
-2. A jupyterhub_config file.
-3. Authentication and other libraries required by the specific jupyterhub_config file.
-
-## Steps to test it outside a cluster
-
-- start configurable-http-proxy in another container
-- specify CONFIGPROXY_AUTH_TOKEN env in both containers
-- put both containers on the same network (e.g. docker network create jupyterhub; docker run ... --net jupyterhub)
-- tell jupyterhub where CHP is (e.g. c.ConfigurableHTTPProxy.api_url = 'http://chp:8001')
-- tell jupyterhub not to start the proxy itself (c.ConfigurableHTTPProxy.should_start = False)
-- Use a dummy authenticator for ease of testing. Update following in jupyterhub_config file
-  - c.JupyterHub.authenticator_class = 'dummyauthenticator.DummyAuthenticator'
-  - c.DummyAuthenticator.password = "your strong password"
