+## 先决条件和构建
+
+由于本项目是以 monorepo 的形式组织的，因此如何构建它的说明可以在每种语言实现的子目录中找到。此外，由于 [rocketmq-apis](https://github.com/apache/rocketmq-apis) 作为一个子模块被包含在本项目中，可能会被一些语言绑定构建时所引用，因此我们强烈建议使用以下命令克隆此存储库：
+
+```sh
+git clone --recursive [email protected]:apache/rocketmq-clients.git
+```
+
 ## 参与贡献

+## Prerequisite and Build
+
+As this project is structured as a monorepo, instructions on how to build it can be found in the subdirectories for each language's bindings. Since the [rocketmq-apis](https://github.com/apache/rocketmq-apis) submodule is included in this project and may be referenced by some bindings, we strongly recommend that you clone this repository using the following command:
+
+```sh
+git clone --recursive [email protected]:apache/rocketmq-clients.git
+```
+
