+## Using multiple Kubernetes clusters **[PREMIUM]**
+
+When using Auto DevOps, you may want to deploy different environments to
+different Kubernetes clusters. This is possible due to the 1:1 connection that
+[exists between them](../../user/project/clusters/index.md#multiple-kubernetes-clusters).
+
+In the [Auto DevOps template](https://gitlab.com/gitlab-org/gitlab-ci-yml/blob/master/Auto-DevOps.gitlab-ci.yml)
+(used behind the scenes by Auto DevOps), there are currently 3 defined environment names that you need to know:
+
+- `review/` (every environment starting with `review/`)
+- `staging`
+- `production`
+
+Those environments are tied to jobs that use [Auto Deploy](#auto-deploy), so
+except for the environment scope, they would also need to have a different
+domain they would be deployed to. This is why you need to define a separate
+`AUTO_DEVOPS_DOMAIN` variable for all the above
+[based on the environment](../../ci/variables/README.md#limiting-environment-scopes-of-variables).
+
+The following table is an example of how the three different clusters would
+be configured.
+
+| Cluster name | Cluster environment scope | `AUTO_DEVOPS_DOMAIN` variable value | Variable environment scope | Notes |
+| ------------ | -------------- | ----------------------------- | ------------- | ------ |
+| review       |  `review/*`    | `review.example.com`  | `review/*`      | The review cluster which will run all [Review Apps](../../ci/review_apps/index.md). `*` is a wildcard, which means it will be used by every environment name starting with `review/`. |
+| staging      |  `staging`     | `staging.example.com` | `staging`       | (Optional) The staging cluster which will run the deployments of the staging environments. You need to [enable it first](#deploy-policy-for-staging-and-production-environments). |
+| production   |  `production`  | `example.com`         | `production`    | The production cluster which will run the deployments of the production environment. You can use [incremental rollouts](#incremental-rollout-to-production). |
+
+To add a different cluster for each environment:
+
+1. Navigate to your project's **Operations > Kubernetes** and create the Kubernetes clusters
+   with their respective environment scope as described from the table above.
+
+    ![Auto DevOps multiple clusters](img/autodevops_multiple_clusters.png)
+
+1. After the clusters are created, navigate to each one and install Helm Tiller
+   and Ingress.
+1. Make sure you have [configured your DNS](#auto-devops-base-domain) with the
+   specified Auto DevOps domains.
+1. Navigate to your project's **Settings > CI/CD > Variables** and add
+   the `AUTO_DEVOPS_DOMAIN` variables with their respective environment
+   scope.
+
+    ![Auto DevOps domain variables](img/autodevops_domain_variables.png)
+
+Now that all is configured, you can test your setup by creating a merge request
+and verifying that your app is deployed as a review app in the Kubernetes
+cluster with the `review/*` environment scope. Similarly, you can check the
+other environments.
