# 第一步

最简单的 FastAPI 文件可能像下面这样：

{* ../../docs_src/first_steps/tutorial001.py *}

将其复制到 `main.py` 文件中。

运行实时服务器：

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev <u style="text-decoration-style:solid">main.py</u>

             Searching for package file structure from directories
