+### Mesh Trackables ###
+
+Mesh trackable are supported on iOS through ARKit.
+
+ARKit can track meshes that are defined in the .arobject format. Such an object can be scanned with the sample application provided here : https://developer.apple.com/documentation/arkit/arkit_in_ios/content_anchors/scanning_and_detecting_3d_objects
+
+Unity serializes .arobject into ARKitReferenceObjectEntry in the editor. ARKitReferenceObjectEntry cannot then be imported at runtime from a .arobjject file. Dynamic loading is not supported yet.
+
+To support adding .arobject without recompiling the full application, we use a dedicated AssetBundle (named "arfmeshes"). To do so:
+* Place you .arobject in the Assets Folder. For instance under Assets/ARObjects
+* Associate the ARKitReferenceObjectEntry with the arfmeshes AssetBundle in the editor
+* Build the AssetBundles. For that you can use the following menu: ARF--> Build AssetBundles iOS
+* Pace the "arfmeshes" file in the Unity persistent data path of the application on the user device.
+
+The name of the Trackable in the World Storage must correspond to the name of the ARKitReferenceObjectEntry.
