+
+Cliconf plugins are abstactions over the CLI interface to network devices. They provide a standard interface
+for Ansible to execute tasks on those network devices.
+
+These plugins generally correspond one-to-one to network device platforms. The appropriate cliconf plugin will
+thus be automatically loaded based on the ``ansible_network_os`` variable.
+
+.. _enabling_cliconf:
+

+
+Using cliconf plugins
+------------------------
+
+The cliconf plugin to use is determined automatically from the ``ansible_network_os`` variable. There should be no reason to override this functionality.
+
+Most cliconf plugins can operate without configuration. A few have additional options that can be set to impact how
+tasks are translated into CLI commands.
+
+Plugins are self-documenting. Each plugin should document its configuration options.

+
+Httpapi plugins tell Ansible how to interact with a remote device's HTTP-based API and execute tasks on the
+device.
+
+Each plugin represents a particular dialect of API. Some are platform-specific (Arista eAPI, Cisco NXAPI), while
+others might be usable on a variety of platforms (RESTCONF).
