+# Operating CORD
+
+This guide defines various processes and procedures for operating a
+CORD POD. It assumes the [build-and-install](../README.md) has already
+completed, and you want to operate and manage a running POD.
+
+Today, CORD most often runs for demo, development, or evaluation
+purposes, so this guide is limited to simple procedures suitable for
+such settings. We expect more realistic operational scenarios will be
+supported in the future.
+
+It is also the case that CORD's operations and management interface
+is primarily defined by its Northbound API. The RESTful version of
+this API is documented [here](rest_apis.md)
+
+This API is auto-generated from a set of models, where CORD's
+model-based design is describe [elsewhere](../xos/README.md).

+A RESTful interface is available for configuring and controlling XOS. It is

+# XOS Internals
+
+XOS is the component of CORD that implements the control plane
+through which operators control and manage CORD. This normally
+happens through a set of XOS-generated interfaces:
+
+* [TOSCA](../xos-tosca/README.md)
+* [REST API](rest_apis.md)
+* [XOSSH](../xos/dev/xossh.md)
+
+This section describes XOS internals, including how it is configured and
+deployed on a running POD. Additional information about how to write
+XOS models (from which these interfaces are generated) is
+described [elsewhere](../xos/README.md) in thie guide.
