# content_for_header

> The content_for_header Liquid object, which outputs the scripts Shoplazza requires and must be placed inside the head tag of a theme layout file.

Dynamically returns all scripts required by Shoplazza.

Include the `content_for_header` object in your [layout files](/docs/theme/architecture/layouts/overview) between the `<head>` and `</head>` HTML tags.

You shouldn't try to modify or parse the `content_for_header` object because the contents are subject to change, which can change the behavior of your code.

:::note
The `content_for_header` object is required in `theme.liquid`.

  	<!-- ... -->
  	{{ content_for_header }}
