+## helm-tiller Addon
+[Kubernetes Helm](https://helm.sh) - The Kubernetes Package Manager
+
+### Enabling helm-tiller
+To enable this addon, simply run:
+
+```shell script
+minikube addons enable helm-tiller
+```
+
+In a minute or so tiller will be installed into your cluster. You could run `helm init` each time you create a new minikube instance or you could just enable this addon.
+Each time you start a new minikube instance tiller will be automatically installed. 
+
+### Testing installation
+
+```shell script
+helm ls
+```
+
+If everything wen't well you shouldn't get any errors about tiller not being installed in your cluster. If you haven't deployed any releases `helm ls` won't return anything.
+
+### Deprecation of Tiller
+When tiller is finally deprecated this addon won't be necessary anymore. If your version of helm doesn't use tiller, you don't need this addon.
