## Escrevendo templates { #writing-templates }

Então você pode escrever um template em `templates/item.html`, por exemplo:

```jinja hl_lines="7"
{!../../docs_src/templates/templates/item.html!}
```

### Valores de contexto do template { #template-context-values }

No código HTML que contém:

{% raw %}

```jinja
Item ID: {{ id }}
```

{% endraw %}
