-## Custom Docker daemon options
+If your organization uses a proxy server to connect to the internet, you may
+need to configure the Docker daemon to use the proxy server. The daemon uses
+a proxy server to access images stored on Docker Hub and other registries,
+and to reach other nodes in a Docker swarm.
 
-Most configuration options for the Docker daemon are set using the `daemon.json`
-configuration file. See [Docker daemon configuration overview](./index.md) for
-more information.
+This page describes how to configure a proxy for the Docker daemon. For
+instructions on configuring proxy settings for the Docker CLI, see [Configure
+Docker to use a proxy server](../../network/proxy.md).
 
-## Manually create the systemd unit files
+There are two ways you can configure these settings:
 
-When installing the binary without a package manager, you may want to integrate
-Docker with systemd. For this, install the two unit files (`service` and
-`socket`) from
-[the GitHub repository](https://github.com/moby/moby/tree/master/contrib/init/systemd)
-to `/etc/systemd/system`.
