+### Usage in CMake
+
+The library provides a Config file for CMake, once installed it can be found via `find_package`.
+
+Which, when successful, will add library target called `Vulkan::Headers` which you can use via the usual `target_link_libraries` mechanism.
+
+```cmake
+find_package(VulkanHeaders REQUIRED CONFIG)
+
+target_link_libraries(foobar PRIVATE Vulkan::Headers)
