+## Usage with Tailwind Prettier Plugin
+
+There's a Tailwind Prettier Plugin to format classes in a certain way. This plugin bundles `prettier-plugin-svelte`, so if you want to use the Tailwind plugin, uninstall `prettier-plugin-svelte` and use the Tailwind plugin instead. If you are using VS Code, make sure to have the Prettier extension installed and switch the default formatter for Svelte files to it.
