* Es gibt ein Unterverzeichnis `app/routers/` mit einer weiteren Datei `__init__.py`, es handelt sich also um ein „Python-Subpackage“: `app.routers`.
* Die Datei `app/routers/items.py` befindet sich in einem Package, `app/routers/`, also ist sie ein Submodul: `app.routers.items`.
* Das Gleiche gilt für `app/routers/users.py`, es ist ein weiteres Submodul: `app.routers.users`.

* Здесь также находится подкаталог `app/routers/`, содержащий `__init__.py`.  Он является суб-пакетом: `app.routers`.
* Файл `app/routers/items.py` находится внутри пакета `app/routers/`. Таким образом, он является суб-модулем: `app.routers.items`.
* Точно также `app/routers/users.py` является ещё одним суб-модулем: `app.routers.users`.

* There's a subdirectory `app/routers/` with another file `__init__.py`, so it's a "Python subpackage": `app.routers`.
* The file `app/routers/items.py` is inside a package, `app/routers/`, so, it's a submodule: `app.routers.items`.
* The same with `app/routers/users.py`, it's another submodule: `app.routers.users`.

* Há um subdiretório `app/routers/` com outro arquivo `__init__.py`, então ele é um "subpacote Python": `app.routers`.
* O arquivo `app/routers/items.py` está dentro de um pacote, `app/routers/`, portanto, é um "submódulo": `app.routers.items`.

This tells Traefik to listen on port 9999 and to use another file `routes.toml`.

/// tip

We are using port 9999 instead of the standard HTTP port 80 so that you don't have to run it with admin (`sudo`) privileges.

///

Now create that other file `routes.toml`:

```TOML hl_lines="5  12  20"

// registerAdminRouter - Add handler functions for each service REST API routes.

* `dependencies`: to include ✨ router-level dependencies ✨ that apply to all the *path operations* in a router. Up to now, this was only possible with `include_router`.
* `callbacks`: OpenAPI callbacks that apply to all the *path operations* in this router.
* `deprecated`: to mark all the *path operations* in a router as deprecated.
