 ### Install MarkLogic Cluster
-Once MarkLogic Operator Pod is running, use your custom manifests or choose from sample manifests from this repository located in the ./config/samples directory. For example, to deploy marklogic single group, use the `quick_start.yaml` from the samples: 
-```sh
-kubectl apply -f quick_start.yaml
-```
+Once MarkLogic Operator Pod is running, use your custom manifests or choose from sample manifests from this repository located in the ./config/samples directory.
+Optionally, create a dedicated namespace for new MarkLogic resources.
+  ```sh
+  kubectl create namespace <namespace-name>
+  ```
+To deploy marklogic single group, use the `quick_start.yaml` from the config/samples: 
+  ```sh
+  kubectl apply -f quick_start.yaml --namespace=<namespace-name>
+  ```
 Once the installation is complete and the pod is in a running state, the MarkLogic Admin UI can be accessed using the port-forwarding command:
 
-  ```shell
+  ```sh
   kubectl port-forward <pod-name> 8000:8000 8001:8001 --namespace=<namespace-name>
   ```
 
 If you used the automatically generated admin credentials, use these steps to extract the admin username, password, and wallet-password from a secret:
 
 1. Run this command to fetch all of the secret names:
-  ```shell
+  ```sh
   kubectl get secrets --namespace=<namespace-name>
   ```
 The MarkLogic admin secret name is in the format  `<marklogicCluster-name>-admin`. For example if markLogicCluster name is `single-node`, the secret name is `single-node-admin`.
 
 2. Using the secret name from step 1, retrieve the MarkLogic admin credentials using these commands:
-  ```shell
+  ```sh
   kubectl get secret single-node-admin --namespace=<namespace-name> -o jsonpath='{.data.username}' | base64 --decode; echo
 
   kubectl get secret single-node-admin --namespace=<namespace-name> -o jsonpath='{.data.password}' | base64 --decode; echo

 ## Known Issues and Limitations
 
 1. The latest released version of fluent/fluent-bit:3.2.5 has high and critical security vulnerabilities. If you decide to enable the log collection feature, choose and deploy the fluent-bit or an alternate image with no vulnerabilities as per your requirements.
 2. Known Issues and Limitations for the MarkLogic Server Docker image can be viewed using the link: https://github.com/marklogic/marklogic-docker?tab=readme-ov-file#Known-Issues-and-Limitations.
