+
+This section describes how to enable Istio and start using it in your projects.
+
+If you use Istio for traffic management, you will need to allow external traffic to the cluster. In that case, you will need to follow all of the steps below.
+
+# Prerequisites
+
+This guide assumes you have already [installed Rancher,]({{<baseurl>}}/rancher/v2.6/en/installation) and you have already [provisioned a separate Kubernetes cluster]({{<baseurl>}}/rancher/v2.6/en/cluster-provisioning) on which you will install Istio.
+
+The nodes in your cluster must meet the [CPU and memory requirements.]({{<baseurl>}}/rancher/v2.6/en/istio/resources/)
+
+The workloads and services that you want to be controlled by Istio must meet [Istio's requirements.](https://istio.io/docs/setup/additional-setup/requirements/)
+
+
+# Install
+
+> **Quick Setup** If you don't need external traffic to reach Istio, and you just want to set up Istio for monitoring and tracing traffic within the cluster, skip the steps for [setting up the Istio gateway]({{<baseurl>}}/rancher/v2.6/en/istio/setup/gateway) and [setting up Istio's components for traffic management.]({{<baseurl>}}/rancher/v2.6/en/istio/setup/set-up-traffic-management)
