+### With Tailwind
+
+In `tailwind.config.js`, set the dark mode property to class:
+
+```js
+// tailwind.config.js
+module.exports = {
+  darkMode: "class",
+};
+```
+
+⚡🎉Ready to use dark mode in Tailwind!
+
+> Caution: Your class must be `"dark"`, which is the default value used in this library. Tailwind requires the class name `"dark"` for dark-theme.
+
+Use dark-mode specific classes:
+
+```tsx
+<h1 className="text-black dark:text-white">
+```
