+### Nexo
+When defining item-based cosmetics, if you prefer to configure and generate everything using Nexo you can simply tell each item cosmetic to reference a Nexo item by using the `Item` field instead of the `Model` field:
 ```
-  - cosmeticemote{emote=DAB} @Self ~onUse
+BASIC_HAT:
+  Item: "nexo:basic_hat"
+  Display: '<green>Basic Hat'
+  Description:
+  - "<white>Just a basic hat"
 ```
