+Vulkan-Hpp provides a [C++ named module](https://en.cppreference.com/w/cpp/language/modules), `vulkan` in [`vulkan.cppm`](vulkan/vulkan.cppm).
 C++ modules are intended to supersede header files. Modules have potential to drastically improve compilation times for large projects, as declarations and definitions may be easily shared across translation units without repeatedly parsing headers.
 Vulkan-Hpp has some extremely long headers (e.g. [`vulkan_structs.hpp`](vulkan/vulkan_structs.hpp)), and the C++ module is likely to shorten compile times for projects currently using it.

 Finally, supply the macro `VULKAN_HPP_DEFAULT_DISPATCH_LOADER_DYNAMIC_STORAGE` exactly once in your source code, just as in the non-module case. In order to have that macro available, include [`vulkan_hpp_macros.hpp`](vulkan/vulkan_hpp_macros.hpp), a lightweight header providing all Vulkan-Hpp related macros and defines. And as explained above, you need to initialize that dispatcher in two or three steps:
 
 ```cpp
-import vulkan_hpp;
+import vulkan;
 
 #include <vulkan/vulkan_hpp_macros.hpp>
