Mapbox actively promotes React Native for AR

[Gnative]

Found this interesting that Mapbox is promoting React Native for AR on their features page - https://www.mapbox.com/augmented-reality

It links to this repo https://github.com/mapbox/react-native-mapbox-ar with the last commit on Jul 2, 2018 ..

Is this AR sdk no longer being maintained? I tried looking for a good start guide but was not able to fine one. Was wondering if anyone had found a good resources?
