 A Universal app is distributed in two parts: the server-side code that serves up the initial application, and the client-side code that's loaded in dynamically.
 
+Universal 应用分为两个部分：提供初始应用的服务端代码，以及动态加载的客户端代码。
+
 The Angular CLI outputs the client-side code in the `dist` directory by default, so you modify the `outputPath` for the __build__ target in the `angular.json` to keep the client-side build outputs separate from the server-side code. The client-side build output will be served by the Express server.
 
+Angular CLI 默认会输出 `dist` 目录中的客户端代码，因此你要修改 `angular.json` 中**构建目标**的 `outputPath`，来把客户端的构建目标和服务端的分开。
+客户端构建的输出将会用 Express 提供服务。
