+#### Dark mode detection
+
+Storybook 7 uses `prefers-color-scheme` to detects your system's dark mode preference if a theme is not set.
+
+Earlier versions used the light theme by default, so if you don't set a theme and your system's settings are in dark mode, this could surprise you.
+
+To learn more about theming, read our [documentation](https://storybook.js.org/docs/react/configure/theming).
