+# About the Sail Operator
+
+The Sail Operator is able to install and manage the lifecycle of the Istio 
+control plane in an OpenShift cluster.
+
+
+## Prerequisites
+
+You have deployed a cluster on OpenShift Container Platform 4.13 or later.
+
+You are logged in to the OpenShift Container Platform web console as a user with 
+the `cluster-admin` role.
+
+You have access to the OpenShift CLI (oc).
+
+
+## Installing the Sail Operator
+
+1. Navigate to the OperatorHub.
+
+1. Click **Operator** -> **Operator Hub**.
+
+1. Search for "sail".
+
+1. Locate the Sail Operator, and click to select it.
+
+1. When the prompt that discusses the community operator appears, click **Continue**.
+
+1. Verify the Sail Operator is version 0.1, and click **Install**.
+
+1. Use the default installation settings presented, and click **Install** to continue.
+
+1. Click **Operators** -> **Installed Operators** to verify that the Sail Operator 
+is installed. `Succeeded` should appear in the **Status** column.
+
+
+## Deploying Istio
+
+To deploy Istio, you must create two resources: `Istio` and `IstioCNI`. The 
+`Istio` resource deploys and configures the Istio Control Plane, whereas the 
+`IstioCNI` resource deploys and configures the Istio CNI plugin. You should 
+create these resources in separate projects. 
+
+
+### Creating the istio-system and istio-cni Projects
+
+1. In the OpenShift Container Platform web console, click **Home** -> **Projects**. 
+
+1. Click **Create Project**.
+
+1. At the prompt, you must enter a name for the project in the **Name** field. 
+For example, `istio-system`. The Operator deploys Istio to the project you 
+specify. The other fields provide supplementary information and are optional.
+
+1. Click **Create**.
+
+Repeat the process to create a project named `istio-cni`.
+
+
+### Creating the Istio resource
+
+1. In the OpenShift Container Platform web console, click **Operators** -> **Installed Operators**. 
+1. Select the `istio-system` project from the **Namespace** drop-down menu.
+1. Click the Sail Operator.
+1. Click **Istio**.
+1. Click **Create Istio**.
+1. Click **Create**. This action deploys the Istio control plane.
+1. When `State: Healthy` appears in the `Status` column, Istio is successfully deployed.
+
+
+### Creating the IstioCNI resource
+
+1. In the OpenShift Container Platform web console, click **Operators** -> **Installed Operators**. 
+1. Click the Sail Operator.
+1. Click **IstioCNI**.
+1. Click **Create IstioCNI**.
+1. Ensure that the name is `default`.
+1. Select the `istio-cni` project from the **Namespace** drop-down menu.
+1. Click **Create**. This action deploys the Istio CNI plugin.
+1. When `State: Healthy` appears in the `Status` column, the Istio CNI plugin is successfully deployed.
+
+
+### Selecting the Istio and IstioCNI versions
+
+The `version` field of the `Istio` and `IstioCNI` resource defines which version 
+of each component should be deployed. This can be set using the `Istio Version` 
+drop down menu when creating a new `Istio` with the OpenShift Container Platform 
+web console. For a list of available versions, see the [versions.yaml](/versions.yaml) file
+or use the command:
+
+```sh
+$ kubectl explain istio.spec.version
+```
+
+### Customizing Istio configuration
+
+The `spec.values` field of the `Istio` and `IstioCNI` resource can be used to 
+customize Istio and Istio CNI plugin configuration using Istio's `Helm` 
+configuration values. When you create this resource using the OpenShift 
+Container Platform web console, it is pre-populated with configuration settings 
+to enable Istio to run on OpenShift.
+
+To view or modify the `Istio` resource from the OpenShift Container Platform web console:
+
+1. Click **Operators** -> **Installed Operators**.
+1. Click **Istio** in the **Provided APIs** column.
+1. Click `Istio` instance, "istio-sample" by default, in the **Name** column.
+1. Click **YAML** to view the `Istio` configuration and make modifications.
+
+An example configuration:
+
+```
+apiVersion: sailoperator.io/v1alpha1
+kind: Istio
+metadata:
+  name: example
+spec:
+  version: v1.20.0
+  values:
+    global:
+      mtls:
+        enabled: true
+      trustDomainAliases:
+      - example.net
+    meshConfig:
+      trustDomain: example.com
+      trustDomainAliases:
+      - example.net
+```
+
+For a list of available configuration for the `spec.values` field, run the 
+following command:
+
+```sh
+$ kubectl explain istio.spec.values
+```
+
+For the `IstioCNI` resource, replace `istio` with `istiocni` in the command above.
+
+Alternatively, refer to [Istio's artifacthub chart documentation](https://artifacthub.io/packages/search?org=istio&sort=relevance&page=1) for:
+
+- [Base parameters](https://artifacthub.io/packages/helm/istio-official/base?modal=values)
+- [Istiod parameters](https://artifacthub.io/packages/helm/istio-official/istiod?modal=values)
+- [Gateway parameters](https://artifacthub.io/packages/helm/istio-official/gateway?modal=values)
+- [CNI parameters](https://artifacthub.io/packages/helm/istio-official/cni?modal=values)

+
+## Installing the istioctl tool
+
+The `istioctl` tool is a configuration command line utility that allows service 
+operators to debug and diagnose Istio service mesh deployments.
+
+For installation steps, refer to the following [link](../docs/common/install-istioctl-tool.md).
+
+## Installing the Bookinfo Application
+
+You can use the `bookinfo` example application to explore service mesh features. 
+Using the `bookinfo` application, you can easily confirm that requests from a 
+web browser pass through the mesh and reach the application.
+
+For installation steps, refer to the following [link](../docs/common/install-bookinfo-app.md).
+
+
+## Creating and Configuring Gateways
+
+The Sail Operator does not deploy Ingress or Egress Gateways. Gateways are not 
+part of the control plane. As a security best-practice, Ingress and Egress 
+Gateways should be deployed in a different namespace than the namespace that 
+contains the control plane.
+
+You can deploy gateways using either the Gateway API or Gateway Injection methods. 
+
+For installation steps, refer to the following [link](../docs/common/create-and-configure-gateways.md).
+
+
+## Istio Addons Integrations
+
+Istio can be integrated with other software to provide additional functionality 
+(More information can be found in: https://istio.io/latest/docs/ops/integrations/). 
+The following addons are for demonstration or development purposes only and 
+should not be used in production environments:
+
+For installation steps, refer to the following [link](../docs/common/istio-addons-integrations.md).
