+Triple-O Deployment Architecture
+================================
+
+Apex is based on the OpenStack Triple-O project as distributed by
+the RDO Project. It is important to understand the basics
+of a Triple-O deployment to help make decisions that will assist in
+successfully deploying OPNFV.
+
+Triple-O stands for OpenStack On OpenStack. This means that OpenStack
+will be used to install OpenStack. The target OPNFV deployment is an
+OpenStack cloud with NFV features built-in that will be deployed by a
+smaller all-in-one deployment of OpenStack. In this deployment
+methodology there are two OpenStack installations. They are referred
+to as the undercloud and the overcloud. The undercloud is used to
+deploy the overcloud.
+
+The undercloud is the all-in-one installation of OpenStack that includes
+baremetal provisioning capability. The undercloud will be deployed as a
+virtual machine on a jumphost. This VM is pre-built and distributed as part
+of the Apex RPM.
+
+The overcloud is OPNFV. Configuration will be passed into undercloud and
+the undercloud will use OpenStack's orchestration component, named Heat, to
+execute a deployment that will provision the target OPNFV nodes.
+
+OPNFV Scenario Architecture
+===========================
+
+OPNFV distinguishes different types of SDN controllers, deployment options, and
+features into "scenarios". These scenarios are universal across all OPNFV
+installers, although some may or may not be supported by each installer.
+
+The standard naming convention for a scenario is:
+<VIM platform>-<SDN type>-<feature>-<ha/noha>
+
+The only supported VIM type is "OS" (OpenStack), while SDN types can be any
+supported SDN controller. "feature" includes things like ovs_dpdk, sfc, etc.
+"ha" or "noha" determines if the deployment will be highly available. If "ha"
+is used at least 3 control nodes are required.
+
+OPNFV Scenarios in Apex
+=======================
+
+Apex provides pre-built scenario files in /etc/opnfv-apex which a user can
+select from to deploy the desired scenario. Simply pass the desired file to
+the installer as a (-d) deploy setting. Read further in the Apex documentation
+to learn more about invoking the deploy command. Below is quick reference
+matrix for OPNFV scenarios supported in Apex. Please refer to the respective
+OPNFV Docs documentation for each scenario in order to see a full scenario
+description. The following scenarios correspond to a supported <Scenario>.yaml
+deploy settings file:
