# generate a new app using create-react-app
yarn create react-app my-app --typescript
cd my-app

# install storybook cli
yarn add -D @storybook/cli

# initialize with storybook cli
yarn sb init

yarn sb init should not be called with the --type react flag. Without --type, the cli figures out the correct type on its own.

The correct type for an app created with create-react-app is react_scripts.

Check out the source code for available types.
