-The `useDropzone` hook just binds the necessary handlers to create a drag 'n' drop zone.
-Use the `getRootProps()` fn to get the props required for drag 'n' drop and use them on any element.
-For click and keydown behavior, use the `getInputProps()` fn and use the returned props on an `<input>`.
-
-Furthermore, the hook supports folder drag 'n' drop by default. See [file-selector](https://github.com/react-dropzone/file-selector) for more info about supported browsers.
