# Overview HoloKit Unity SDK enables Unity developers to build StAR (Stereoscopic Augmented Reality) apps on HoloKit. There are two main functionalities provided by HoloKit Unity SDK, which are stereoscopic rendering and hand tracking. Stereoscopic rendering allows the user to see the virtual content in a holographic way, and hand tracking enables the user to interact with the virtual content with their hands. HoloKit SDK Unity is compatible with ARFoundation, which helps experienced AR developers quickly get started to build StAR apps.
