+Using Live Components in Reusable Bundles
+-----------------------------------------
+
+`Symfony Bundles`_ let you reuse features across many different Symfony
+applications. However, you **cannot include live components in reusable
+bundles** to make them available in any application that installs the bundle.

+components inside reusable bundles. Their implementation relies on unsupported
+hacks that could break at any time, so Symfony does not recommend using this
+approach.
