+# Unity VR Sample
+
+> This demo is based on meta oculus's [Ultimate Glove Ball](https://github.com/oculus-samples/Unity-UltimateGloveBall) VR demo.
+
+
+This sample show off how to use [Azure Realtime Transport for Unity](https://github.com/wanlwanl/multiplayer-community-contributions/tree/wanl/transport/Transports/com.community.netcode.transport.azure-realtime) and use Live Trace tool to monitor events in real time of an existing VR game in simple configuration. The underlying connection of the network replication is via Websockets. This is useful especially for WebGL platform since UDP is not available on it.
