 %description
-This project provides the Khronos official Vulkan ICD desktop 
+Vulkan is an explicit API, enabling direct control over how
+GPUs actually work. As such, Vulkan supports systems that have
+multiple GPUs, each running with a different driver, or ICD
+(Installable Client Driver). Vulkan also supports multiple global
+contexts (instances, in Vulkan terminology). The ICD loader is a
+library that is placed between a Vulkan application and any number
+of Vulkan drivers, in order to support multiple drivers and the
+instance-level functionality that works across these drivers.
+Additionally, the loader manages inserting Vulkan layer libraries,
+such as validation layers, between an application and the drivers. 
+
+This package provides the Khronos official Vulkan ICD desktop
 loader for Windows, Linux, and MacOS.
