 This can be achieved by following the steps below. For convenience of discussion, we assume that the domain is originally created by the following example command, where `/path/to/weblogic-operator-output-directory` is a directory that is created in advance to store the files that are generated by the operator.
 
 ```
-      ./create-weblogic-domain.sh \
-        -i create-domain-job-inputs.yaml \
-        -o /path/to/weblogic-operator-output-directory
-
+./create-weblogic-domain.sh \
+  -i create-domain-job-inputs.yaml \
+  -o /path/to/weblogic-operator-output-directory
 ```
 
 * Delete the domain using the [Delete WebLogic domain resources](kubernetes/delete-weblogic-domain-resources.sh) script.
 
 ```
-      ./delete-weblogic-domain-resources.sh -d <domainUID>
+./delete-weblogic-domain-resources.sh -d <domainUID>
 
 ````
 * Delete the contents of the physical volume using the appropriate tools.
-* Delete the contents in the `weblogic-domains/<domainUID>` directory under `/path/to/weblogic-operator-output-directory`, which is used in the previous run of the [Create WebLogic domain](kubectles/create-weblogic-domain.sh) script. 
+* Delete the contents in the `weblogic-domains/<domainUID>` directory under the output directory that is used when the domain is originally created, which is `/path/to/weblogic-operator-output-directory` in our example.
 * Modify the create WebLogic domain inputs file `create-domain-job-inputs.yaml`.
-* Recreate all resources that are labeled with the `domainUID`, but are NOT created by the [Create WebLogic domain](kubernetes/create-weblogic-domain.sh) script. One example of such resources is the `secret` for the domain credentials, which often is created manually and may be labeled with `domainUID`. Any resources that are not labeled with the `domainUID` is not deleted by the [Delete WebLogic domain resources](kubernetes/delete-weblogic-domain-resources.sh) script, and therefore, do not need to be recreated.

-If for some reason the last step failed, repeat the steps above after deleting the failed create WebLogic domain job using the following command. The `<output-dir>` is the directory that is passed to the create WebLogic domain script via `-o`. It is `/path/to/weblogic-operator-output-directory` in our example.
