+Therefore, **use [Lucide icons](https://lucide.dev/)!**
+There are only two exceptions: use `search` and `translate` from [Hero icons v1 (outline version)](https://v1.heroicons.com/) instead of the alternatives from Lucide.

-  - Historical note: this is a fork and superset of [Feather icons](https://feathericons.com/), which is not maintained anymore.
-    Lucide contains a lot more icons.
-    Even if Feather icons are identical to Lucide, always import the Lucide icon for code consistency!
-- In special cases, you can use icons from [Hero icons v1 (outline version)](https://v1.heroicons.com/).
-  Those icons look visually very similar to Lucide icons.
-  Still: there should be a good reason for not using Lucide!
-  Currently, there are two important exceptions in which you should use the Hero icons:
-  - Hero's `search` is better than the one from Lucide, which is too stubby and looks like a Q.
-  - Hero's `translate` is much better than Lucides `languages` and more on point than `globe`.

-Should your app require an icon that's not available in Lucide or Hero, you can create a new one.
+Should your app require an icon that's not available in Lucide, you can create a new one (or check Hero).
 This should follow [Lucide's Design Principles](https://lucide.dev/guide/design/icon-design-guide).
 Unless the icon is very particular (i.e. unlikely to be useful in any other application), it should be [contributed back to Lucide](https://github.com/lucide-icons/lucide/blob/main/CONTRIBUTING.md).
