 The .map file can be placed in the Unity persistent data path of the application on the user device with the following name: "ARkitWorlMap.map". Alternatively, the variable keyvalueTags of the Trackable can also contain a parameter with the "url" key providing a link to download the map file.
 
-By default, the origin of the Map Trackable is the point (0, 0 ,0). If the Map includes an Anchor, you can use it as the origin by setting the name of the Trackable in the World Storage with the TrackableId of the ARAnchor stored in the map. https://docs.unity3d.com/Packages/com.unity.xr.arfoundation@5.1/api/UnityEngine.XR.ARSubsystems.TrackableId.html
+The map needs to include at least one Anchor. You can use one of them as the origin of the map by setting the name of the Trackable in the World Storage with the TrackableId of the ARAnchor stored in the map. https://docs.unity3d.com/Packages/com.unity.xr.arfoundation@5.1/api/UnityEngine.XR.ARSubsystems.TrackableId.html
