+Page TSconfig can be defined on a site level by placing a file called
+:file:`page.tsconfig` in the storage directory of the site

+:ref:`site sets <t3coreapi:site-sets>` by placing a a file called :file:`page.tsconfig`

 entries or by polluting global scope. Dependencies can be expressed via site sets,
 allowing for automatic ordering and deduplication.
