 ## Overview
 
-Starworld is an Overte client that renders virtual world entities inside the StardustXR compositor. It bridges Overte's entity protocol with Stardust's spatial computing environment, allowing you to view and interact with Overte domains in XR.
+Starworld is an [Overte](https://overte.org) client that renders virtual world entities inside the [StardustXR](https://stardustxr.org) compositor. It bridges Overte's entity protocol with Stardust's spatial computing environment, allowing you to view and interact with Overte domains in XR.
 
 **Current Status:** ✨ **3D model rendering with HTTP asset downloading!** Entities render as GLTF/GLB models loaded from the local cache. ModelCache automatically downloads models from http:// and https:// URLs to `~/.cache/starworld/models/`. Primitive models (cube, sphere, suzanne) are pre-generated in `~/.cache/starworld/primitives/` using Blender.
 
+### About the Technologies
+
+**[StardustXR](https://stardustxr.org)** is a next-generation XR display server and compositor that runs XR clients as separate processes. It provides a Unix-philosophy approach to XR, where each application is an independent process communicating via IPC.
