```console
    $ mkdocs serve --dev-addr 8008
    ```

Now you can go to <a href="http://127.0.0.1:8008" class="external-link" target="_blank">http://127.0.0.1:8008</a> and see your changes live.

You will see that every language has all the pages. But some pages are not translated and have an info box at the top, about the missing translation.

    ```console
    $ cd docs/en/
    ```

    Führen Sie dann `mkdocs` in diesem Verzeichnis aus:

    ```console
    $ mkdocs serve --dev-addr 8008
    ```

#### Typer-CLI (optional)

Die Anleitung hier zeigt Ihnen, wie Sie das Skript unter `./scripts/docs.py` direkt mit dem `python` Programm verwenden.

!!! tip
    或者你也可以手动执行和该脚本一样的操作

    进入语言目录，如果是英文文档，目录则是 `docs/en/`:

    ```console
    $ cd docs/en/
    ```

    在该目录执行 `mkdocs` 命令

    ```console
    $ mkdocs serve --dev-addr 8008
    ```

#### Typer CLI （可选）

本指引向你展示了如何直接用 `python` 运行 `./scripts/docs.py` 中的脚本。

    os.environ["LINENUMS"] = "true"
    if lang is None:
        lang = "en"
    lang_path: Path = docs_path / lang
    os.chdir(lang_path)
    mkdocs.commands.serve.serve(dev_addr="127.0.0.1:8008")


def get_updated_config_content() -> Dict[str, Any]:
    config = get_en_config()
    languages = [{"en": "/"}]
    new_alternate: List[Dict[str, str]] = []

...the prefix must not include a final `/`.

So, the prefix in this case is `/items`.

We can also add a list of `tags` and extra `responses` that will be applied to all the *path operations* included in this router.

And we can add a list of `dependencies` that will be added to all the *path operations* in the router and will be executed/solved for each request made to them.

## Den Hintergrundtask hinzufügen

Übergeben Sie innerhalb Ihrer *Pfadoperation-Funktion* Ihre Taskfunktion mit der Methode `.add_task()` an das *Hintergrundtasks*-Objekt:

```Python hl_lines="14"
{!../../../docs_src/background_tasks/tutorial001.py!}
```

`.add_task()` erhält als Argumente:

* Eine Taskfunktion, die im Hintergrund ausgeführt wird (`write_notification`).

This is not required by Couchbase, but is a good practice that will help you afterwards.

```Python hl_lines="9"
{!../../../docs_src/nosql_databases/tutorial001.py!}
```

## Add a function to get a `Bucket`

In **Couchbase**, a bucket is a set of documents, that can be of different types.

They are generally all related to the same application.
