-Vulkan is a low-level cross-platform 3D graphics and compute API.
-
-This port provides the official validation layers for Vulkan applications,
-which are useful for development and debugging.
+Vulkan is an Explicit API, enabling direct control over how GPUs
+actually work. By design, minimal error checking is done inside a
+Vulkan driver. Applications have full control and responsibility for
+correct operation. Any errors in how Vulkan is used can result in a
+crash. This project provides Vulkan validation layers that can be
+enabled to assist development by enabling developers to verify their
+applications correct use of the Vulkan API.
