[Thanks for the guide! I recently created a new project with expo-router and I was confused with the app/ folder One suggestion tho my launch script looks like this "storybook": "sb-rn-get-stories && EXPO\_PUBLIC\_STORYBOOK\_ENABLED='true' expo start", and the index.tsx page const storybookEnabled = process.env.EXPO\_PUBLIC\_STORYBOOK\_ENABLED; I don't have .env file, no need to manually edit, it's faster to swap between the app or the storybook with yarn start yarn storybook](https://hashnode.com/posts/using-storybook-with-expo-router-v2-sdk-49-typescript/64b022fe0ba7115b2af1d9ce/comment/6529464d2f8d4e00663bb3fe)
