+Installation Guide
+==================
+
+Abstract
+--------
+
+This document describes how to install the Non-RT RIC components, their dependencies and required system resources.
+
+Software Installation and Deployment
+------------------------------------
+
+Install with Helm
++++++++++++++++++
+
+Helm charts and an example recipe are provided in the `it/dep repo <https://gerrit.o-ran-sc.org/r/admin/repos/it/dep>`_,
+under "nonrtric". By modifying the variables named "installXXX" in the beginning of the example recipe file, which
+components that will be installed can be controlled. Then the components can be installed and started by running the
+following command:
+
+      .. code-block:: bash
+
+        bin/deploy-nonrtric -f nonrtric/RECIPE_EXAMPLE/example_recipe.yaml
+
+Install with dependent components
++++++++++++++++++++++++++++++++++
+
+The scripts for the deployments of rApp Manager and its dependent components are available in *rappmanager/scripts/install* directory.
+
+ACM components should be configured with couple of other components for the participants to work.
+
+In case some of the installation is already setup or not set by the installation scripts, the below environment variables can be used to set the configurations ACM through installation scripts.
