-      It is also possible to install the binaries individually. For example to install traefik only:
-
-      ```
-      $ python3 -m jupyterhub_traefik_proxy.install --traefik --output=/usr/local/bin
-      ```
+      This will install the default versions of traefik, to to `/usr/local/bin` specified through the `--output` option.
 
       If no directory is passed to the installer, a *dependencies* directory will be created in the `traefik-proxy` directory. In this case, you **must** add this directory to `PATH`, e.g.
 
       ```
       $ export PATH=$PATH:{$PWD}/dependencies

+## Installing a key-value store
+
+If you want to use a key-value store to mediate configuration
+(mainly for use in distributed deployments, such as containers),
+you can get etcd or consul via their respective release pages:
+
+* Install [`etcd`](https://github.com/etcd-io/etcd/releases)
+
+* Install [`consul`](https://github.com/hashicorp/consul/releases)
+
+Or, more likely, select the appropriate container image.
+You will also need to install a Python client for the Key-Value store of your choice:

+- `etcdpy`
+- `python-consul2`
