+The **ric-infra** group is expected to be deployed in each Kubernetes cluster. It
+consists of components such as Kong ingress controller, Helm chart repo, Tiller for
+xApp deployment, as well as various credentials. This group is deployed in both the
+RIC and AUX clusters.
+
+The **ric-platform** group is deployed in the RIC cluster. It consists of all Near
+Realtime RIC Platform components, including:
+
+- DBaaS
+- E2 Termination
+- E2 Manager
+- A1 Mediator
+- Routing Manager
+- Subscription Manager
+- xApp manager
+- VESPA Manager
+- Jaeger Adapter
+- Resource Status Manager
+
+The **ric-aux** group is deployed in the AUX cluster. It consists of components that
+facilitate the operation of Near Realtime RIC and receiving inputs from the Near Realtime
+RIC. In Amber release, this group includes the following:
+
+- ONAP VES Collector
+- ONAP DMaaP Message Router
+- RIC Dashboard
+
+In addition, this group also include ONAP AAF and ONAP Portal.

+Directory Structure
+-------------------
+
+The directories of the it/dep repo is organized as the following.
+
+::
+
+ |-- LICENSES.txt
+ |-- README.md
+ |-- RECIPE_EXAMPLE
+ |-- bin
+ |-- ci
+ |-- docs
+ |-- etc
+ |-- ric-aux
+ | |-- 80-Auxiliary-Functions
+ | |-- 85-Ext-Services
+ | `-- README.md
+ |-- ric-common
+ | |-- Common-Template
+ | |-- Docker-Credential
+ | |-- Helm-Credential
+ | `-- Initcontainer
+ |-- ric-infra
+ | |-- 00-Kubernetes
+ | |-- 15-Chartmuseum
+ | |-- 20-Monitoring
+ | |-- 30-Kong
+ | |-- 40-Credential
+ | |-- 45-Tiller
+ | `-- README.md
+ |-- ric-platform
+ | |-- 50-RIC-Platform
+ | |-- 55-Ext-Services
+ | `-- README.md
+ `-- tox.ini
+
+The deployment artifacts of these deployment groups are placed under the ric-infra,
+ric-platform, and ric-aux directories. These directories are structured similarly
+where underneath each group is a list of numbered sub-groups. The numbering is
+based on the order that how different sub-groups would be deployed within the same
+Kubernetes cluster. For example, the 50-RIC-Platform subgroup should be deployed
+before the 55-Ext-Services subgroup. And all subgroups in the ric-infra group
+should be deployed before the sub-groups in the ric-platform group, as indicated
+by they sub-group numbers being lower than those of the ric-platform group.
+
+Within each numbered subgroup, there is a **helm** directory and a **bin** directory.
+The bin directory generally contains the install and uninstall script for deploying
+all the Helm charts of the subgroup. The helm directory contains the helm charts
+for all the components within the subgroup.
+
+At the top level, these is also a bin directory, where group level deployment and
+undeployment scripts are located. For example, the **deploy-ric-platform** script
+iterates all the subgroups under the ric-platform group, and calls the install script
+of each subgroup to deploy the components in each subgroup.
+
+Recipes
+--------
+**Recipe** is an important concept for Near Realtime RIC deployment. Each
+deployment group has its own recipe. Recipe provides a customized specification
+for the components of a deployment group for a specific dpeloyment site. The
+RECIPE_EXAMPLE directory contains the example recipes for the three deployment
+groups.
