 Create a GKE cluster in which you'll install Agones. You can use
 [GKE Standard mode](#create-a-standard-mode-cluster-for-agones)
 or [GKE Autopilot mode](#create-an-autopilot-mode-cluster-for-agones).
+You can read more about choosing a [cluster mode above](#choosing-a-gke-cluster-mode).

+### Create an Autopilot mode cluster for Agones
+
+1. Choose a [Release Channel]({{<ref "/docs/Guides/Best Practices/gke.md#release-channels" >}}) (Autopilot clusters must be on a Release Channel).
+
+1. Create the cluster:
+
+    ```bash
+    gcloud container clusters create-auto [CLUSTER_NAME] \
+      --region=[COMPUTE_REGION] \
+      --release-channel=[RELEASE_CHANNEL] \
+      --autoprovisioning-network-tags=game-server
+    ```
+
+Replace the following:
+* `[CLUSTER_NAME]`: The name of your cluster.
+* `[COMPUTE_REGION]`: the GCP region to create the cluster in.
+* `[RELEASE_CHANNEL]`: one of `rapid`, `regular`, or `stable`, chosen [above](#choosing-a-release-channel-and-optional-version). The default is `regular`.
+
+Flag explanations:
+* `--region`: The compute region [you chose above](#choosing-a-gke-cluster-mode).
+* `--release-channel`: The release channel [you chose above](#choosing-a-release-channel-and-optional-version).
+* `--autoprovisioning-network-tags`: Defines the tags that will be attached to new nodes in the cluster. This is to grant access through ports via the [firewall created above](#creating-the-firewall).

 * `--machine-type`: The type of machine to use for nodes. Default: `e2-standard-4`. Depending on the needs of your game, you may wish to [have smaller or larger machines](https://cloud.google.com/compute/docs/machine-types).
 * `--num-nodes`: The number of nodes per cluster zone. For regional clusters, `--num-nodes=1` creates one node in 3 separate zones in the region, giving you faster recovery time in the event of a node failure.

 ## Setting up cluster credentials
 
 `gcloud container clusters create` configurates credentials for `kubectl` automatically. If you ever lose those, run:
