-Users are able to **export** and **import** services between clusters with [Multi-cluster Service APIs](https://github.com/kubernetes-sigs/mcs-api).
+用户能够通过[多集群服务API](https://github.com/kubernetes-sigs/mcs-api)在集群之间导出和导入服务。 
 
-## Prerequisites
+## 准备开始
 
-### Karmada has been installed
+### 安装Karmada
 
-We can install Karmada by referring to [quick-start](https://github.com/karmada-io/karmada#quick-start), or directly run `hack/local-up-karmada.sh` script which is also used to run our E2E cases.
+我们可以通过参考[快速开始](https://github.com/karmada-io/karmada#quick-start)来安装Karmada，或者直接运行 `hack/local-up-karmada.sh` 脚本，我们的E2E测试执行正是使用了该脚本。
 
-### Member Cluster Network
 
-Ensure that at least two clusters have been added to Karmada, and the container networks between member clusters are connected.
+### 成员集群网络
 
-- If you use the `hack/local-up-karmada.sh` script to deploy Karmada, Karmada will have three member clusters, and the container networks of the `member1` and `member2` will be connected.
-- You can use `Submariner` or other related open source projects to connected networks between member clusters.
+确保至少有两个集群被添加到 Karmada，并且成员集群之间的容器网络可相互连接。
 
-### The ServiceExport and ServiceImport CRDs have been installed
+- 如果你使用 `hack/local-up-karmada.sh` 脚本来部署 Karmada，Karmada 将有三个成员集群，`member1` 和 `member2` 的容器网络将被连接。
+- 你可以使用 `Submariner` 或其他相关的开源项目来连接成员集群之间的网络。
 
-We need to install ServiceExport and ServiceImport in the member clusters.
+### 安装 ServiceExport 和 ServiceImport CRD
 
-After ServiceExport and ServiceImport have been installed on the **karmada control-plane**, we can create `ClusterPropagationPolicy` to propagate those two CRDs to the member clusters.
+我们需要在成员集群中安装ServiceExport和ServiceImport。
+
+在**karmada控制平面**上安装完 ServiceExport 和 ServiceImport 之后，我们可以创建 `ClusterPropagationPolicy` 来分发这两个 CRD 到成员集群。
