+### Hashing Vulkan types
+
+With the additional header `vulkan_hash.hpp`, you get specializations of `std::hash` for the handle wrapper classes and, with C++14, for the structure wrappers. With `VULKAN_HPP_HASH_COMBINE`, you can define your own hash combining algorithm for the structure elements.
+
 ### Samples and Tests
 
 When you configure your project using CMake, you can enable SAMPLES_BUILD to add some sample projects to your solution. Most of them are ports from the LunarG samples, but there are some more, like CreateDebugUtilsMessenger, InstanceVersion, PhysicalDeviceDisplayProperties, PhysicalDeviceExtensions, PhysicalDeviceFeatures, PhysicalDeviceGroups, PhysicalDeviceMemoryProperties, PhysicalDeviceProperties, PhysicalDeviceQueueFamilyProperties, and RayTracing. All those samples should just compile and run.
