 ### Face Mesh
 
-To use face mesh filters just add the `FaceMesh Texture` or `FaceMesh Video` component to a object in the scene and assign it to the filters in your filter manager component. Make sure to select the correct layout for your texture or video (wether you used procreate or the mediapipe/google face layout when you created your texture).
+Use Procreate or any other 2D painting app like Photoshop to create Facemesh filters - no need to write any code. For quickly testing you can drop your own artwork on the website to use as a filter.

Make sure to select the correct layout for your texture or video (wether you used Procreate/arkit or the mediapipe/google face layout when you created your texture).
 
 ### Animations
 
 To make your animation react to faces simply create `Float` parameters and use [ARKit blendshape names](https://developer.apple.com/documentation/arkit/arfaceanchor/blendshapelocation). For example `jawOpen` has a value between 0 (closed) and 1 (open), `eyeBlinkLeft` and `eyeBlinkRight` for blinking. You can use the `Face Filter Animator` component to see all options. Example: "Facefilter/Examples/Open Mouth.prefab"
