+## FAQ
+### Does YouTube work on Quest?
+No. There is no mechanism to support YouTube videos on Quest reasonably that will not be broken by VRChat the momement it is implemented.
+
+### Are videos supported on Quest?
+Yes, kind of. You must have a direct link to a .mp4 video for videos to work on Quest. This is because Quest does not have YouTubeDL which is needed to resolve links that are not pointing directly to a video file. Which is why YouTube is not supported.
