The Newspack Themes include support for Yoast Breadcrumbs.
Enable Yoast Breadcrumbs
Yoast Breadcrumbs can be turned and configured on your site by following these steps on their website.
Once enabled, the breadcrumbs will appear immediately below the header. In some cases — like when a post uses the Featured Image Behind Post Title or Featured Image Beside Post Title settings — the breadcrumbs will not be visible on an individual post.
