 # QuickStart

+# 快速起步
+
 Good tools make application development quicker and easier to maintain than
 if you did everything by hand.

+好的工具能让开发更加简单快捷。
+
 The [**Angular CLI**](https://cli.angular.io/) is a **_command line interface_** tool
 that can create a project, add files, and perform a variety of ongoing development tasks such
 as testing, bundling, and deployment.

+[**Angular CLI**](https://cli.angular.io/)是一个**命令行界面**工具，它可以创建项目、添加文件以及执行一大堆开发任务，比如测试、打包和发布。
+
 The goal in this guide is to build and run a simple Angular
 application in TypeScript, using the Angular CLI
 while adhering to the [Style Guide](guide/styleguide) recommendations that
 benefit _every_ Angular project.

+在这一章CLI快速起步中，我们的目标是构建并运行一个超级简单的Angular应用。我们会使用Angular-CLI来让每个Angular应用从[风格指南](guide/style-guide)中获益。
+
 By the end of the chapter, you'll have a basic understanding of development with the CLI
 and a foundation for both these documentation samples and for real world applications.

+在本章的末尾，我们会通过CLI对开发过程有一个最基本的理解，并将其作为其它文档范例以及真实应用的基础。

 [the Angular CLI repository](https://github.com/angular/angular-cli) and
 [Wiki](https://github.com/angular/angular-cli/wiki).

+你首先要看的文件是`README.md`。
