 All projects within a workspace share this configuration context. 
 Project-specific [TypeScript](https://www.typescriptlang.org/) configuration files inherit from the workspace-wide `tsconfig.*.json`, and app-specific [TSLint](https://palantir.github.io/tslint/) configuration files inherit from the workspace-wide `tslint.json`.
 
+工作空间中的所有项目都共享这个配置上下文。
+每个项目自己的 [TypeScript](https://www.typescriptlang.org/) 配置文件继承自工作空间级的 `tsconfig.*.json`，而每个项目自己的 [TSLint](https://palantir.github.io/tslint/) 配置文件也继承自工作空间级的 `tslint.json`。

 ### Default app project files
 
+### 默认应用工程文件
+
 The CLI command `ng new my-app` creates a workspace folder named "my-app" and generates a new app skeleton. 
 This initial app is the *default app* for CLI commands (unless you change the default after creating additional apps). 
 
+CLI 命令 `ng new my-app` 创建了一个名叫 "my-app" 的工作空间目录，并生成了一个新应用的骨架。
+这个初始应用是 CLI 命令的*默认应用*（除非你在创建了其它应用之后修改了默认应用）。
+
 A newly generated app contains the source files for a root module, with a root component and template. 
 When the workspace file structure is in place, you can use the `ng generate` command on the command line to add functionality and data to the initial app.
 
+新生成的应用包含根模块和一个根组件及其模板的代码。
+当工作空间的文件结构就绪之后，你可以在命令行上运行 `ng generate` 命令，来给这个初始应用添加功能和数据。
+
 <div class="alert is-helpful>
 
  Besides using the CLI on the command line, You can also use an interactive development environment like [Angular Console](https://angular.console.com), or manipulate files directly in the app's source folder and configuration files.
 
+ 除了在命令行上使用 CLI 之外，你还可以使用像 [Angular Console](https://angular.console.com) 这样的交互开发环境，或者直接操纵应用的源码目录中的源码文件和配置文件。
+

 The `src/` subfolder contains the source files (app logic, data, and assets), along with configuration files for the initial app.
 Workspace-wide `node_modules` dependencies are visible to this project.
