+Introduction
+============
 
+This document describes the steps to install an OPNFV Colorado reference
+platform, as defined by the Genesis Project using the Apex installer.
+
+The audience is assumed to have a good background in networking
+and Linux administration.
+
+Preface
+=======
+
+Apex uses Triple-O from the RDO Project OpenStack distribution as a
+provisioning tool. The Triple-O image based life cycle installation
+tool provisions an OPNFV Target System (3 controllers, n number of
+compute nodes) with OPNFV specific configuration provided by the Apex
+deployment tool chain.
+
+The Apex deployment artifacts contain the necessary tools to deploy and
+configure an OPNFV target system using the Apex deployment toolchain.
+These artifacts offer the choice of using the Apex bootable ISO
+(``opnfv-apex-colorado.iso``) to both install CentOS 7 and the
+necessary materials to deploy or the Apex RPMs (``opnfv-apex*.rpm``)
+which expects installation to a CentOS 7 libvirt enabled host. The RPM
+contains a collection of configuration files, prebuilt disk images,
+and the automatic deployment script (``opnfv-deploy``).
+
+An OPNFV install requires a "Jumphost" in order to operate.  The bootable
+ISO will allow you to install a customized CentOS 7 release to the Jumphost,
+which includes the required packages needed to run ``opnfv-deploy``.
+If you already have a Jumphost with CentOS 7 installed, you may choose to
+skip the ISO step and simply install the (``opnfv-apex*.rpm``) RPMs. The RPMs
+are the same RPMs included in the ISO and include all the necessary disk
+images and configuration files to execute an OPNFV deployment. Either method
+will prepare a host to the same ready state for OPNFV deployment.
+
+``opnfv-deploy`` instantiates a Triple-O Undercloud VM server using libvirt
+as its provider.  This VM is then configured and used to provision the
+OPNFV target deployment (3 controllers, n compute nodes).  These nodes can
+be either virtual or bare metal. This guide contains instructions for
+installing either method.
