@slightlyoffbeat: I see you added a card for the Unity WebVR Assets in 7cf342a:

two small requests:

1. could you add this as the background-image of the card?

   

2. could we have the "Unity WebVR Assets" heading dual as a link to the Unity asset package (https://assetstore.unity.com/packages/templates/systems/webvr-assets-109152)? or feel free to add a "Get it Now" button next to "Get Started" - or replace the link. whatever you think is best.
