+# RIC Infrastructure Support
+  
+Helm charts, configuration files, and automation scripts that deploy a development enviroment for RIC.
+A developer should star from here to create a kubernetes cluster that is pre-configured for RIC.
+Such development cluster is mimicking a closed field-trial environment. 
+
+
+
+### Directory Structure
+.
+├── 00-Kubernetes             Contains scripts to deploy K8S cluster
+├── 10-Nexus                  Contains scripts and helm charts to deploy the docker registry and helm repo
+└── README.md                 This file
+
+
+### To deploy the Kubernetes cluster
+```sh
+$ # Modify the configuration files in ./00-Kubernetes/etc/
+$ . ./00-Kubernetes/bin/install
+```
+
+### To deploy Nexus repo manager
+```sh
+$ # Modify the configuration files in ./10-Nexus/etc/
+$ . ./10-Nexus/bin/install
+```
+
+
+### Nexus Deployment Options
+You can configure the Helm release name, Kubernetes namespace, and specify ingress controller port using configuration
+files located in ./10-Nexus/etc/
+
+In the one-click deployment solution, the above setting will be overrided by environment variables shown below.
+*RICINFRA_RELEASE_NAME
+*RICINFRA_NAMESPACE
+*INGRESS_PORT
+
+
+### Passing credential to RIC
+The installation process of the Nexus repo manager will generate certificates and credential for docker registry and
+helm repo.
+
+TODO: Fill in the details about how to pass the credential to RIC
