- Storybook's CLI provides support for both [Yarn](https://yarnpkg.com/) and [npm](https://www.npmjs.com/) package managers. If you have Yarn installed in your environment but prefer to use npm as your default package manager add the `--use-npm` flag to your installation command. For example: ```shell npx storybook init --use-npm ``` - Add the `--type preact` flag to the installation command to set up Storybook manually: ```shell npx sb init --type preact ``` - For other installation issues, check the [Preact README](../../app/preact/README.md) for additional instructions.
