+## Assets
+
+You can add assets to your stories by adding a `stories` folder in the `/server` directory.  
+All the assets in this folder will be available as public assets with the prefix `/stories`.  
+You can use it like the `/public` folder in the Nuxt app, but the folder will be available only when the stories are available too.
