+## TailwindCSS v4
+
+We upgraded the TailwindCSS version from v3 to v4. If you have written custom markup with Tailwind classes you should read the Tailwind v4 [Upgrade Guide](https://tailwindcss.com/docs/upgrade-guide#changes-from-v3) so you know which breaking changes were introduced. Thankfully, the team behind Tailwind provide an automated [Upgrade Tool](https://tailwindcss.com/docs/upgrade-guide#using-the-upgrade-tool). Run it with the following command:
+
+```bash
+$ npx @tailwindcss/upgrade
+```
