 # Vulkan Ecosystem Components\r
 *Version 1.0, January 25, 2016*\r
 \r
-This project provides loader and validation layers for Vulkan developers on Windows and Linux.\r
+This project provides Khronos offical ICD loader and validation layers for Vulkan developers on Windows and Linux.\r
 \r
 ## Introduction\r
 \r
-Vulkan is an Explicit API, enabling direct control over how GPUs actually work. No (or very little) validation or error checking is done inside a VK driver. Applications have full control and responsibility. Any errors in how VK is used are likely to result in a crash. This project provides layered utility libraries to ease development and help guide developers to proven safe patterns.\r

 \r
-New with Vulkan is an extensible layered architecture that enables validation libraries to be implemented as layers. The loader is essential in supporting multiple drivers and GPUs along with layer library enablement.\r
+Vulkan supports multiple GPUs and multiple global contexts (VkInstance). The ICD loader is necessary to support multiple GPUs  and the VkInstance level Vulkan commands.  Additionally, the loader manages inserting Vulkan layer libraries,\r
+including validation layers between the application and the ICD.\r
