+# Newspack UI Storybook
+
+This directory contains the Storybook implementation for Newspack UI components. Storybook is a development environment for UI components, allowing you to browse a component library, view the different states of each component, and interactively develop and test components.
+
+## Running Storybook
+
+From the plugin root directory:
+
+```bash
+npm run storybook
+```
+
+This will open Storybook in your default browser at `http://localhost:6006`.
+
+## Available Scripts
+
+- `npm run storybook` - Start Storybook development server
+- `npm run build-storybook` - Build static Storybook for deployment
+
+## Troubleshooting
+
+Common issues and solutions:
+
+1. **Storybook fails to start**
+   - Check Node.js version
+   - Clear npm cache: `npm cache clean --force`
+   - Delete node_modules and reinstall: `rm -rf node_modules && npm install`
+
+2. **Stories not appearing**
+   - Verify file naming follows conventions
+   - Check story export format
+   - Clear Storybook cache: `rm -rf node_modules/.cache/storybook`
+
+3. **Styles not loading**
+   - Verify style imports
+   - Check webpack configuration
+   - Clear browser cache
