-If you are using 3D models, include `@babylonjs/loaders` and ensure it is registered.
+## Models
+If you are using 3D models ensure you have added the `@babylonjs/loaders` NPM.  It is not a direct dependency, but registers loaders as plugins via imports with side effects:
+* Register **all** model types `import @babylonjs/loaders;`
+* OBJ `import '@babylonjs/loaders/OBJ';`
+* glTF `import '@babylonjs/loaders/glTF';`
+
+*(more instructions on model loading in ES6 [here](https://doc.babylonjs.com/divingDeeper/developWithBjs/treeShaking#loaders) )*
 
 # Usage Styles
 `react-babylonjs` tries to remain unopinionated about how you integrate BabylonJS with React.  This module provides a 100% declarative option and/or you can customise by adding code.  There are lots of escape hatches where you can switch to imperative coding and direct access to objects.

 ## Hooks renamed `useBabylonScene` -> `useScene`, `useBabylonEngine` -> `useEngine` & `useBabylonCanvas` --> `useCanvas`
 `model` intrinsic host element has been removed in favour of a `Model` component (notice the lower case vs. proper case), which needs to be enclosed in `React.Suspense` Component.
