 ## Key concepts 
 
-<!-- Content? -->
+The `player` sample application lets you customize the remote player experience using public APIs and the latest Holographic Remoting packages. If you don't need customization, use the [pre-packaged version on the Microsoft Store](https://www.microsoft.com/p/holographic-remoting-player/9nblggh4sv40).
+
+Use the `remote` and `remote_openxr` samples to implement remoting functionality into a custom engine using C++. If you're using Unity or Unreal, this feature is already built-in.
 
 ## Best practices
 
-<!-- Content? -->
+Check out the [Holographic Remoting Player documentation](https://docs.microsoft.com/windows/mixed-reality/develop/platform-capabilities-and-apis/holographic-remoting-player) for information on quality, performance, diagnostics, and system requirements.
