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
