+  How to install CAP Operator using CAP Operator Manager in a Kubernetes cluster
+---
+
+To install the CAP Operator using CAP Operator Manager, please execute the following commands:
+
+```bash
+kubectl apply -f https://github.com/SAP/cap-operator-lifecycle/releases/latest/download/manager_manifest.yaml
+```
+
+The above command will create namespace `cap-operator-system` with CAP Operator Manager installed. Once the CAP Operator Manager pod is running, you can install the CAP operator by executing the following command:
+
+```bash
+kubectl apply -n cap-operator-system -f https://github.com/SAP/cap-operator-lifecycle/releases/latest/download/manager_default_CR.yaml
+```
+**This would work only if the `ingressGatewayLabels` in your clusters matches the following values**
+
+```yaml
+ingressGatewayLabels:
+  - name: istio
+    value: ingressgateway
+  - name: app
+    value: istio-ingressgateway
+```
+
+If not, you will have to manually create the `CAPOperator` resource. For more details on the same, please refer to [link](https://sap.github.io/cap-operator-lifecycle/docs/installation/local-cluster/).
