-## Tailwind Just-In-Time
-
-Tailwind recently released [@tailwindcss/jit](https://blog.tailwindcss.com/just-in-time-the-next-generation-of-tailwind-css) to make the web development much faster.
-
-To activate the option:
-- create and modify your custom `tailwind.config.js` as mentioned in [the tailwind's documentation](https://tailwindcss.com/docs/just-in-time-mode#enabling-jit-mode)
-- then override the purge config directly into the `tailwind.config.js` file to select the file to want to watch
-
-
-```ts [tailwind.config.js]
-module.exports = {
-  mode: 'jit'
-}
-```
-
-_The double tilde to mention the Nuxt config file is an alias to the root directory which could be different from the sources directory._

-Restart your Nuxt server and see how fast it is now ⚡️
