+**Loading xApp Helm Charts**
+
+The RIC Platform App Manager deploys RIC applications (a.k.a. xApps) using Helm charts stored in a private local Helm repo.
+The Helm local repo is deployed as a sidecar of the App Manager pod, and its APIs are exposed using an ingress controller with TLS enabled.
+You can use both HTTP and HTTPS to access it.
+
+Before any xApp can be deployed, its Helm chart must be loaded into this private Helm repo.
+The example below shows the command sequences that upload and delete the xApp Helm charts:
+
+#. Load the xApp Helm charts into the Helm repo;
+#. Verify the xApp Helm charts;
+#. Call App Manager to deploy the xApp;
+#. Call App Manager to delete the xApp;
+#. Delete the xApp helm chart from the private Helm repo.
+
+In the following example, the <INGRESS_CONTROLLER_IP> is the IP address that the RIC cluster ingress controller is listening to.
+If you are using a VM, it is the IP address of the main interface.
+If you are using REC clusters, it is the DANM network IP address you assigned in the recipe.
+If the commands are executed inside the host machine, you can use "localhost" as the <INGRESS_CONTROLLER_IP>.
