-Google offers an add-on for GKE,

-To determine if the add-on is right for you, refer to [Istio on GKE](https://cloud.google.com/istio/docs/istio-on-gke/overview)
-for more information.
+Google 为 GKE 提供了一个插件，
+您可以使用它来代替手动安装 Istio。

-    The default installation of Mixer requires nodes with >1 vCPU. If you are
-    installing with the
-    [demo configuration profile](/docs/setup/additional-setup/config-profiles/),
-    you can remove the `--machine-type` argument to use the smaller `n1-standard-1` machine size instead.
