+Installing Near Realtime RIC in RIC Cluster
+===========================================
+
+Getting and Preparing Deployment Scripts
+----------------------------------------
+
+Run the following commands in a root shell:
+
+.. code:: bash
+
+  git clone http://gerrit.o-ran-sc.org/r/it/dep
+  cd RECIPE_EXAMPLE
+
+Edit the recipe files RIC_INFRA_RECIPE_EXAMPLE and RIC_PLATFORM_RECIPE_EXAMPLE.  In particular the following values often need adaptation to local deployments:
+
+1. Docker registry URL;
+2. Docker registry credential;
+3. Helm repo credential;
+4. Component docker container image tags.
+
+
+Deploying the Infrastructure and Platform Groups
+------------------------------------------------
+
+After the recipes are edited, the Near Realtime RIIC is ready to be deployed.
+
+.. code:: bash
+
+  cd dep/bin
+  ./deploy-ric-infra ../RECIPE_EXAMPLE/RIC_INFRA_RECIPE_EXAMPLE
+  ./deploy-ric-platform ../RECIPE_EXAMPLE/RIC_PLATFORM_RECIPE_EXAMPLE 
+
+
+Checking the Deployment Status
+------------------------------
+
+Now check the deployment status and results similar to the below indicate a complete and successful deployment.
+
+.. code::
+
+  # helm list
