 * Create a directory for the generated properties and Kubernetes YAML files for this domain if it does not already exist.  The pathname is `/path/to/weblogic-operator-output-directory/weblogic-domains/<domainUID>`. If the directory already exists, its contents will be removed.
 * Create a properties file, `domain.properties`, in the directory that is created above. This properties file will be used to create a sample WebLogic Server domain.
-* Clone the WebLogic docker-images project into the current directory using `git clone https://github.com/oracle/docker-images.git`.
+* Clone the WebLogic docker-images project into the current directory using `git clone https://github.com/oracle/docker-images.git`. Note, by default, the script always cleans up the project and clones it again on every run. You need to specify the `-k` option if you want to use a previously cloned project.
 * Replace the built-in user name and password in the `properties/docker-build/domain_security.properties` file with the `username` and `password` that are supplied on the command line using the `-u` and `-p` options. These credentials need to match the WebLogic domain admin credentials in the secret that is specified via the `weblogicCredentialsSecretName` property in the `create-domain-inputs.yaml` file.
 * Build a Docker image based on the Docker sample, [Example Image with a WebLogic Server Domain using the Oracle WebLogic Scripting Tooling (WLST)](https://github.com/oracle/docker-images/tree/master/OracleWebLogic/samples/12213-domain-home-in-image) or [Example Image with a WebLogic Server Domain using the Oracle WebLogic Deploy Tooling (WDT)](https://github.com/oracle/docker-images/tree/master/OracleWebLogic/samples/12213-domain-home-in-image-wdt). It will create a sample WebLogic Server domain in the Docker image. **Note**: Oracle recommends keeping the domain home image private in the local repository.
 * Create a tag that refers to the generated Docker image.
