## Documentation Summary and Description - OpenAPI { #documentation-summary-and-description-openapi }

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).

///

FastAPI will now:

* **Validate** the data making sure that the max length is 50 characters
* Show a **clear error** for the client when the data is not valid
* **Document** the parameter in the OpenAPI schema *path operation* (so it will show up in the **automatic docs UI**)

## Alternative (old): `Query` as the default value { #alternative-old-query-as-the-default-value }

    }

    /**
     * Hide empty state
     */
    function hideEmptyState() {
        elements.emptyState.hide();
    }

    /**
     * Show empty state
     */
    function showEmptyState() {
        elements.emptyState.show();
    }

    /**
     * Format timestamp
     */
    function formatTimestamp(date) {
        var hours = date.getHours();

You can set `"json_schema_extra"` with a `dict` containing any additional data you would like to show up in the generated JSON Schema, including `examples`.

/// tip

You could use the same technique to extend the JSON Schema and add your own custom extra info.

    }

    private static List<String> parentCommitsOf(String commit) throws IOException, InterruptedException, ExecutionException {
        String stdout = getStdout(new String[] {"git", "show", "--format=%P", "--no-patch", "--no-show-signature", commit});
        String trimmed = stdout.trim();
        if (trimmed.isEmpty()) {
            return Collections.emptyList();
        }
        return Arrays.stream(trimmed.split("\\s+"))

You can limit the lines used from the docstring of a *path operation function* for OpenAPI.

Adding an `\f` (an escaped "form feed" character) causes **FastAPI** to truncate the output used for OpenAPI at this point.

It won't show up in the documentation, but other tools (such as Sphinx) will be able to use the rest.

## Additional Responses { #additional-responses }

For example, we, the team behind FastAPI, built [**FastAPI Cloud**](https://fastapicloud.com), to make deploying FastAPI apps to the cloud as streamlined as possible, with the same developer experience of working with FastAPI.

I will show you some of the main concepts you should probably keep in mind when deploying a **FastAPI** application (although most of it applies to any other type of web application).
