   block qs-seed
     :marked
       The **QuickStart seed** contains the same application as the QuickStart playground
       and even has <live-example>its own _playground_</live-example> 
       that accomodates development of richer examples in a live coding environment.

  +    **《快速起步》种子** 包含了与《快速起步》游乐场一样的应用，并且它还有<live-example>自己的*游乐场*</live-example>，
  +    用来在在线编程的环境里开发更丰富例子。
       
       But it's true purpose is to provide a solid foundation for _local_ development.
       Consequently, there are _many more files_ in the project folder on your machine, 
       most of which you can [learn about later](setup-systemjs-anatomy.html "Setup Anatomy").
   
  +    但是，它真实的目的是提供坚实的*本地*开发基础。
  +    所以你的电脑里的项目目录里面有*更多文件*，参见[搭建剖析](setup-systemjs-anatomy.html "Setup Anatomy")。

   block core-files

       Focus on the following three TypeScript (`.ts`) files in the **`/app`** folder.
   
  +    注意**`/app`**目录里的下列三个 TypeScript (`.ts`) 文件：
     .filetree
       .file app
       .children
  
positive.code: :marked
    All guides and cookbooks have _at least these core files_. Each file has a distinct purpose and evolves independently as the application grows.

negative.code:         it's the only viable choice for a sample running in a _live-coding_ environment like Plunker.
          You'll learn about alternative compiling and deployment options later in the documentation.
  
          使[即时 (JiT) 编译器](../glossary.html#jit)用编译应用并且在浏览器中[启动](appmodule.html#main "启动应用")并运行应用。
          对于大多数项目的开发，这都是合理的选择。而且它是在像 Plunker 这样的*在线编程*环境中运行例子的唯一选择。
          你将在本文档中学习其他编译和开发选择。
