 ### Getting Function Pointers
 
-A common case for checking the version is in order to find how to correctly get extension function pointers.
+When using a version that has promoted the function, one can just directly use the call.
+
+In the case of enabling the extensions, all the functions for those extensions will call `vkGetDeviceProcAddr` automatically.

-// Create aliased function pointers for 1.0 and 1.1+ contexts
-PFN_vkBindImageMemory2KHR vkBindImageMemory2Function = nullptr;
-if (DeviceValidationVersion() >= VK_API_VERSION_1_1) {

-// later in code
