{* ../../docs_src/sub_applications/tutorial001.py hl[11,19] *}

### 查看文档

如果主文件是 `main.py`，则用以下 `uvicorn` 命令运行主应用：

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)

## Instalar dependências { #install-dependencies }

Certifique-se de criar um [ambiente virtual](../virtual-environments.md){.internal-link target=_blank}, ativá-lo e instalar `jinja2`:

<div class="termy">

```console
$ pip install jinja2

---> 100%
```

</div>

## Usando `Jinja2Templates` { #using-jinja2templates }

* Importe `Jinja2Templates`.
* Crie um objeto `templates` que você possa reutilizar posteriormente.
