-## Using context
-
-If you need to do something fancy with `scene`, `canvas`, or `engine`, there are a few ways:
-
-### react hooks
-
-```jsx
-// use Hooks to get engine/canvas/scene 
-import { useBabylonEngine, useBabylonCanvas, useBabylonScene } from 'react-babylonjs'
-
-// later inside a functional component:
-
-export default () => {
-  const engine = useBabylonEngine()
-  const canvas = useBabylonCanvas()
-  const scene = useBabylonScene()
-  console.log({ engine, canvas, scene })
-
-  return (
-    <div>See console</div>
-  )
-}
-
-````
-
-### HOC
-
-```jsx
-import { withBabylonJS, withScene } from 'react-babylonjs'
-
-const DemoComponent = ({ scene, engine, canvas }} => {
-  console.log({ scene, engine, canvas })
-  return (
-    <div>See console</div>
-  )
-}
-
-export default withBabylonJS(withScene(DemoComponent))
-```
-
-### direct Consmuer
-
-```jsx
-import { WithSceneContext } from 'react-babylonjs'
-
-const DemoComponent = ({ scene }} => {
-  const engine = scene.getEngine()
-  const canvas = engine.getCanvas()
-  console.log({ scene, engine, canvas })
-  return (
-    <div>See console</div>
-  )
-}
-
-export default () => (<WithSceneContext>{DemoComponent}</WithSceneContext>)
-```
