+Bulma is **icon library agnostic**: this means that you can use _any_ icon font library (like Font Awesome 4 or 5, Material Design Icons, Open Iconic, Ionicons…) with Bulma's `icon` class.
+
+As a result, **Bulma already supports Font Awesome 5**! 😃
+
+Since the `icon` element is simply a **container** for any icon font *allowing the layout to reserve a spot for the icon while it loads), it supports any size of Font Awesome 4 and 5.
+
+For the sake of being in sync with Bulima users, I've recently updated the website to actually use Font Awesome 5! The process of **migrating** from Font Awesome 4 to 5 is straightforward. You simply need to:
+
+1. include Font Awesome 5 instead, [using the script tag](https://fontawesome.com/get-started)
+2. replace `fa` classes with their `fas` and `fab` equivalents
+
+That's it!
