+## Installation
+
+### Using SSP operator
+The [SSP operator](https://github.com/kubevirt/ssp-operator) can be configured to install VM Console Proxy together with
+a Route used to expose it to the outside.
+
+### Without SSP operator
+The VM Console Proxy needs to be deployed in the same namespace where Kubevirt is.
+You can use these commands to deploy the latest version:
+```bash
+kubectl apply -n ${KUBEVIRT_NAMESPACE} -f "https://github.com/kubevirt/vm-console-proxy/releases/latest/download/vm-console-proxy.yaml"
