-<details><summary>Additional steps for Air Gap/Private Registry</summary>
-<p>
-
-If you have an Air Gapped network you will need the `tiller` image available in your private registry.
-
-##### Create registry secret
-
-Create a registry secret in the `kube-system` namespace for the `tiller` ServiceAccount to use.
-
-```
-kubectl -n kube-system create secret docker-registry regcred \
---docker-server="reg.example.com" \
---docker-username=<user> \
---docker-password=<password> \
---docker-email=<email>
-```
-
-##### Patch the ServiceAccount
-
-Update the ServiceAccount to include the imagePullSecret. Pods created with this ServiceAccount will automatically have the imagePullSecret added to their manifest.
-
-```
-kubectl -n kube-system patch serviceaccount tiller -p \
-'{"imagePullSecrets": [{"name\": "regcred"}]}'
-```
-
-##### `--tiller-image` option
-
-Add the --tiller-image option to the `helm init` command.
-
-```
---tiller-image reg.example.com/kubernetes-helm/tiller:v2.9.1
-```
