+### Private registry secret creation
+1. In some instances you may wish to manually create a private-registry secret in the namespace or during a helm deployment.  There are a couple of ways to do this:
+
+First is to add the secret manually using the shell:
+
+   ```shell
+   kubectl create secret docker-registry private-registry --docker-server="https://registry1.dso.mil" --docker-username='Username' --docker-password="CLI secret" --docker-email=<your-email> --namespace=<package-namespace>
+   ```
+The second is to create a yaml file containing the secret and apply it during a helm install.  In this example the file name is "reg-creds.yaml"
+
+create the file with the secret contents:
+   ```yaml
+   registryCredentials:
+     registry: registry1.dso.mil
+     username: ""
+     password: ""
+     email: ""
+   ```
+
+and then include a reference to your file during your helm install command by adding
+   ```shell
+   -f reg-creds.yaml
+   ```
