+  Using KubeVirt with minikube
+---
+
+## Prerequisites
+
+- kvm2 driver
+
+### Enable KubeVirt on minikube
+Minikube can be started with default values and those will be enough to run a quick example, that being said, if you can spare a few more GiBs of RAM (by default it uses 2GiB), it’ll allow you to experiment further.
+
+We’ll create a profile for KubeVirt so it gets its own settings without interfering what any configuration you might have already, let’s start by increasing the default memory to 4GiB:
+
+```shell script
+minikube config -p kubevirt set memory 4096
+minikube config -p kubevirt set vm-driver kvm2
+minikube start -p kubevirt
+```
+
+To enable this addon, simply run:
+```shell script
+minikube addons enable kubevirt
+```
+
+In a minute or so kubevirt's default components will be installed into your cluster.
+You can run `kubectl get pods -n kubevirt` to see the progress of the kubevirt installation.
+
+
+### Disable KubeVirt
+To disable this addon, simply run:
+```shell script
+minikube addons disable kubevirt
+```
+
+### More Information
+
+See official [Minikube Quickstart](https://kubevirt.io/quickstart_minikube/) documentation for more information and to install KubeVirt without using the addon.
