# Anatomy of the Setup Project # 搭建项目环境 The documentation [setup](guide/setup) procedures install a _lot_ of files. Most of them can be safely ignored. 在[搭建](guide/setup)本地开发环境的过程中会安装*很多*文件。它们大部分都可以被忽略掉。 Application files _inside the_ **`src/`** and **`e2e/`** folders matter most to developers. 对程序员来讲最重要的是在 *`src/`* 和 *`e2e/`* 文件夹*之内*的应用文件。 Files _outside_ those folders condition the development environment. They rarely change and you may never view or modify them. If you do, this page can help you understand their purpose. 在这两个文件夹*之外*的文件为开发环境设定条件。 这些文件很少会需要变动,你可能永远都不需要阅览或者修改它们。
