 Classnames is a simple Twig function for conditionally joining css class names together in Twig templates, in a way that makes them much more readable. It's like Jed Watson's [Classnames](https://github.com/JedWatson/classnames) but for Twig in Craft.
 
+This plugin is especially useful with Tailwind CSS projects.
+
 ## Requirements
 
-This plugin requires Craft CMS 4.0.0 or later.
+This plugin requires Craft CMS 5.0.0 or later.
 
-For Craft 3 users, [view the v1 branch](https://github.com/vigetlabs/craft-classnames/tree/v1).
+For Craft 4 users, [view the v2 branch](https://github.com/vigetlabs/craft-classnames/tree/v2).
