* If the PR updates one of the internal dependencies, for example it's modifying `requirements.txt` files, or GitHub Action versions, if the tests are passing, the release notes (shown in a summary in the PR) don't show any obvious potential breaking change, you can merge it. 😎

It will all be combined and included in your OpenAPI, and shown in the API docs:

## Combine predefined responses and custom ones { #combine-predefined-responses-and-custom-ones }

You can see those schemas because they were declared with the models in the app.

That information is available in the app's **OpenAPI schema**, and then shown in the API docs.

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

### Hey API { #hey-api }

## Automatic docs { #automatic-docs }

The JSON Schemas of your models will be part of your OpenAPI generated schema, and will be shown in the interactive API docs:

And will also be used in the API docs inside each *path operation* that needs them:

Each specific example `dict` in the `examples` can contain:

* `summary`: Short description for the example.
* `description`: A long description that can contain Markdown text.
* `value`: This is the actual example shown, e.g. a `dict`.
* `externalValue`: alternative to `value`, a URL pointing to the example. Although this might not be supported by as many tools as `value`.

You can use it like this:
