 ### Setup
 
-By default, the Vagrant setup will create a single master VM (called kubernetes-master) and one node (called kubernetes-node-1). Each VM will take 1 GB, so make sure you have at least 2GB to 4GB of free memory (plus appropriate free disk space). To start your local cluster, open a shell and run:

 The `KUBERNETES_PROVIDER` environment variable tells all of the various cluster management scripts which variant to use.  If you forget to set this, the assumption is you are running on Google Compute Engine.

 If you installed more than one Vagrant provider, Kubernetes will usually pick the appropriate one. However, you can override which one Kubernetes will use by setting the [`VAGRANT_DEFAULT_PROVIDER`](https://docs.vagrantup.com/v2/providers/default.html) environment variable:
