That information is available in the app's **OpenAPI schema**, and then shown in the API docs (by Swagger UI).

And that same information from the models that is included in OpenAPI is what can be used to **generate the client code**.

### Generate a TypeScript Client

Now that we have the app with the models, we can generate the client code for the frontend.

#### Install `openapi-ts`

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.

Now let's say that you want to add a translation for the section [Features](features.md){.internal-link target=_blank}.

* Copy the file at:

```
docs/en/docs/features.md
```

* Paste it in exactly the same location but for the language you want to translate, e.g.:

```
