+
+## Details
+
+A [Kubernetes operator](https://kubernetes.io/docs/concepts/extend-kubernetes/operator/) is a design pattern for writing code to automate tasks and extend Kubernetes. An operator is a set of concepts you can use to define a service for Kubernetes and helps to automate administrative services in Kubernetes.
+
+The [Operator Lifecycle Manager module](https://docs.oracle.com/en/operating-systems/olcne/1.9/olm/) installs an instance of [Operator Lifecycle Manager](https://olm.operatorframework.io/) into a Kubernetes cluster to manage the installation and lifecycle of the operators. The Operator Lifecycle Manager references a public upstream operator registry ([https://operatorhub.io](https://operatorhub.io)) to share Operators. 
+
+This tutorial shows how to install the Operator Lifecycle Manager module into your Oracle Cloud Native Environment cluster, followed by an example showing how to install and use an Operator.
+
+### Objectives
+
+In this tutorial, you will learn:
+
+   - To install the `operator-lifecycle-manager` module
+   - Verify the installation of the Operator Manager 
+   - Install additional Operators
+
+### Prerequisites
+
+- Minimum of a 3-node Oracle Cloud Native Environment cluster:
+
+   - Operator node
+   - Kubernetes control plane node
+   - Kubernetes worker node
+
+- Each system should have Oracle Linux installed and configured with:
+
+   - An Oracle user account (used during the installation) with sudo access
+   - Key-based SSH, also known as password-less SSH, between the hosts
+   - Installation of Oracle Cloud Native Environment with the OCI Cloud Controller Manager
