 1. Visit https://console.redhat.com/openshift/token to retrieve your SSO offline authentication token
 
 1. Create a credentials secret within the target namespace with the token to be referenced later by `ROSAControlePlane`

-    kubectl create secret generic rosa-creds-secret \
-        --from-literal=ocmToken='eyJhbGciOiJIUzI1NiIsI....' \

 Alternatively, you can edit CAPA controller deployment to provide the credentials
-```shell
-    kubectl edit deployment -n capa-system capa-controller-manager
-```
-and add the following environment variables to the manager container
-```yaml
-    env:
-      - name: OCM_TOKEN
-        value: "<token>"
-      - name: OCM_API_URL
-        value: "https://api.openshift.com" # or https://api.stage.openshift.com

 ### Migration from offline token to service account authentication
 
 1. Visit [https://console.redhat.com/iam/service-accounts](https://console.redhat.com/iam/service-accounts) and create a new service account.
 
 1. If you previously used kubernetes secret to specify the OCM credentials secret, edit the secret:
-```shell
-    kubectl edit secret rosa-creds-secret
-```
-where you will remove the `ocmToken` credentials and add base64 encoded `ocmClientID` and `ocmClientSecret` credentials like so:
-```yaml
-apiVersion: v1
- data:
-   ocmApiUrl: aHR0cHM6Ly9hcGkub3BlbnNoaWZ0LmNvbQ==
-   ocmClientID: Y2xpZW50X2lk...
-   ocmClientSecret: Y2xpZW50X3NlY3JldA==...
- kind: Secret
- type: Opaque
-```
+    ```shell
+        kubectl edit secret rosa-creds-secret
+    ```
+    where you will remove the `ocmToken` credentials and add base64 encoded `ocmClientID` and `ocmClientSecret` credentials like so:
+    ```yaml
+    apiVersion: v1
+     data:
+       ocmApiUrl: aHR0cHM6Ly9hcGkub3BlbnNoaWZ0LmNvbQ==
+       ocmClientID: Y2xpZW50X2lk...
+       ocmClientSecret: Y2xpZW50X3NlY3JldA==...
+     kind: Secret
+     type: Opaque
+    ```
 
 1. If you previously used capa manager deployment to specify the OCM offline token as environment variable, edit the manager deployment:
-```shell
-    kubectl -n capa-system edit deployment capa-controller-manager
-```
+    ```shell
+        kubectl -n capa-system edit deployment capa-controller-manager
+    ```
 and remove the `OCM_TOKEN` and `OCM_API_URL` variables, followed by `kubectl -n capa-system rollout restart deploy capa-controller-manager`. Then create the new default
 secret in the `capa-system` namespace with:
-```shell
-    kubectl -n capa-system create secret generic rosa-creds-secret \
-      --from-literal=ocmClientID='....' \
-      --from-literal=ocmClientSecret='eyJhbGciOiJIUzI1NiIsI....' \
-      --from-literal=ocmApiUrl='https://api.openshift.com'
-```
+    ```shell
+        kubectl -n capa-system create secret generic rosa-creds-secret \
+          --from-literal=ocmClientID='....' \
+          --from-literal=ocmClientSecret='eyJhbGciOiJIUzI1NiIsI....' \
