+# Driver plugin installation
+
+Minikube uses Docker Machine to manage the Kubernetes VM so it benefits from the
+driver plugin architecture that Docker Machine uses to provide a consistent way to
+manage various VM providers. Minikube embeds VirtualBox and VMware Fusion drivers
+so there are no additional steps to use them. However, other drivers require an
+extra binary to be present in the host PATH.
+
+The following drivers currently require driver plugin binaries to be present in
+the host PATH:
+
+* [KVM](#kvm-driver)
+* [xhyve](#xhyve-driver)
+
+#### KVM driver
+
+Download the `docker-machine-driver-kvm` binary from
+https://github.com/dhiltgen/docker-machine-kvm/releases and put it somewhere in
+your PATH. Minikube is currently tested against `docker-machine-driver-kvm` 0.7.0.
+
+#### xhyve driver
+
+From https://github.com/zchee/docker-machine-driver-xhyve#install:
+
+```
+$ brew install docker-machine-driver-xhyve
+
+# docker-machine-driver-xhyve need root owner and uid
+$ sudo chown root:wheel $(brew --prefix)/opt/docker-machine-driver-xhyve/bin/docker-machine-driver-xhyve
