 In other frameworks, pagination can be very painful. We hope Laravel's approach to pagination will be a breath of fresh air. Laravel's paginator is integrated with the [query builder](/docs/{{version}}/queries) and [Eloquent ORM](/docs/{{version}}/eloquent) and provides convenient, easy-to-use pagination of database records with zero configuration.
 
-By default, the HTML generated by the paginator is compatible with the [Tailwind CSS framework](https://tailwindcss.com/); however, Bootstrap pagination support is also available.

+#### Tailwind JIT
+
+If you are using Laravel's default Tailwind pagination views and the Tailwind JIT engine, you should ensure your application's `tailwind.config.js` file's `content` key references Laravel's pagination views so that their Tailwind classes are not purged:
+
+```js
+content: [
+    './resources/**/*.blade.php',
+    './resources/**/*.js',
+    './resources/**/*.vue',
+    './vendor/laravel/framework/src/Illuminate/Pagination/resources/views/*.blade.php',
+],
+```
