FastAPI will use this `response_model` to do all the data documentation, validation, etc. and also to **convert and filter the output data** to its type declaration.

/// tip

If you have strict type checks in your editor, mypy, etc, you can declare the function return type as `Any`.

That way you tell the editor that you are intentionally returning anything. But FastAPI will still do the data documentation, validation, filtering, etc. with the `response_model`.

* Convert from and to JSON automatically.
* Document everything with OpenAPI, that can be used by:
    * Interactive documentation systems.
    * Automatic client code generation systems, for many languages.
* Provide 2 interactive documentation web interfaces directly.

We just scratched the surface, but you already get the idea of how it all works.

Try changing the line with:

package gradlebuild.docs;

import org.gradle.api.file.ConfigurableFileCollection;
import org.gradle.api.file.DirectoryProperty;

 */
public abstract class UserManual {
    /**
     * The root of the user manual documentation.  This is the source of the adoc files.
     */
    public abstract DirectoryProperty getRoot();
