### Check the docs { #check-the-docs }

Now, if you check the docs, they will show all the additional metadata:

### Order of tags { #order-of-tags }

The order of each tag metadata dictionary also defines the order shown in the docs UI.

For example, even though `users` would go after `items` in alphabetical order, it is shown before them, because we added their metadata as the first dictionary in the list.

* `title`: The OpenAPI title, shown in the docs.
* `version`: The version of your API, e.g. `2.5.0`.
* `openapi_version`: The version of the OpenAPI specification used. By default, the latest: `3.1.0`.
* `summary`: A short summary of the API.
* `description`: The description of your API, this can include markdown and will be shown in the docs.

     * Notification message displayed on the login page.
     * This message is shown to users on the authentication page.

    @Size(max = 3000)
    public String notificationLogin;

    /**
     * Notification message displayed on the search top page.
     * This message is shown to users on the main search page.
     */
    @Size(max = 3000)
    public String notificationSearchTop;

    }

 * <p><b>Do not use this interface</b> for public or protected declarations: it is a fig leaf for
 * bad design, and it does not prevent anyone from using the declaration---and experience has shown
 * that they will. If the method breaks the encapsulation of its class, then its internal
 * representation will be hard to change. Instead, use <a

There are multiple tools that you can use to create those dependables, and they get integrated into OpenAPI so they are shown in the automatic docs UI, they can be used by automatically generated clients and SDKs, etc.

You can import them from `fastapi.security`:

```python
from fastapi.security import (
    APIKeyCookie,
    APIKeyHeader,

To add a summary and description to your *path operations*, and show them in the docs UI, read the docs for [Tutorial - Path Operation Configurations - Summary and Description](../tutorial/path-operation-configuration.md#summary-and-description){.internal-link target=_blank}.
