 ### Mobile support
 
-This asset works by utilizing [Unity's WebGL platform support](https://docs.unity3d.com/2018.1/Documentation/Manual/webgl-gettingstarted.html) and therefore shares the same limitations. Because of this, mobile support is limited and may not work. See [Unity's **WebGL Browser Compatibility** table](https://docs.unity3d.com/2018.1/Documentation/Manual/webgl-browsercompatibility.html).

-For WebVR content to work with the regular release version of Chrome for Android, users will need to [manually enable WebVR and Gamepad extensions](https://webvr.rocks/chrome_for_android#setup) from `chrome://flags`.
-
-Alternatively, sites can register for a [WebVR Origin Trial token](https://webvr.rocks/chrome_for_android#what_is_the_webvr_origin_trial) which will allows the API to be available for whitelisted origins.

+
+This project was heavily influenced by early explorations in using Unity to build for WebVR by [@gtk2k](https://github.com/gtk2k).
+
+Also, thanks to [@arturitu](https://github.com/arturitu) for creating the [3D-hand models](https://github.com/aframevr/assets/tree/gh-pages/controllers/hands) used for controllers in these examples.
