**FastAPI** will **extract** the data for **each field** from the **query parameters** in the request and give you the Pydantic model you defined.

## Check the Docs

You can see the query parameters in the docs UI at `/docs`:

`MINIO_VOLUMES="http://minio{1...2}/data{1...4} http://minio{3...4}/data{1...4}"`, you can remove the first argument `http://minio{1...2}/data{1...4}` to update your `MINIO_VOLUMES` setting, then restart all the servers in the setup in parallel using `systemctl restart minio`.

- On Kubernetes setups, the statefulset specification needs to be modified by changing the command line input for the MinIO container. Once the relevant changes are done, proceed to execute `kubectl apply -f statefulset.yaml`....

## Change the Theme

The same way you could set the syntax highlighting theme with the key `"syntaxHighlight.theme"` (notice that it has a dot in the middle):

{* ../../docs_src/configure_swagger_ui/tutorial002.py hl[3] *}

That configuration would change the syntax highlighting color theme:

## Change Default Swagger UI Parameters

Make sure you [Upgrade the FastAPI version](../deployment/versions.md#upgrading-the-fastapi-versions){.internal-link target=_blank} to at least 0.95.1 before using `Annotated`.

///

## Declare metadata

You can declare all the same parameters as for `Query`.

For example, to declare a `title` metadata value for the path parameter `item_id` you can type:
