+It is usually not necessary to call <info>drupal:scaffold</info> manually,
+because it is called automatically as needed, e.g. after an <info>install</info>
+or <info>update</info> command. Note, though, that only packages explicitly
+allowed to scaffold in the top-level composer.json will be processed by this
+command.
