Definir uma subpasta no templates com o mesmo nome da app.

```
mkdir -p accounts/templates/accounts
```

## Templates

### Lista de itens

```
touch accounts/templates/accounts/user_list.html
```

### Detalhes de um item

```
touch accounts/templates/accounts/user_detail.html
```

### Template de Formulário
