+## Custom author page
+
+By default, the `Byline` component will hyperlink each author's byline to their Reuters.com page, formatted `https://www.reuters.com/authors/{author-slug}/`.
+
+To hyperlink to different pages or email addresses, pass a custom function to the `getAuthorPage` prop.
+
+```svelte
+<!-- Pass a custom function as `getAuthorPage` -->
+<Byline
+  authors={['Dea Bankova', 'Prasanta Kumar Dutta', 'Anurag Rao', 'Mariano Zafra']}
