-### Hiding Vulkan API Symbols
+### Exposing Static Vulkan API Symbols
 
-You can optionally build MoltenVK with the Vulkan API static call symbols (`vk*`) hidden,
-to avoid library linking conflicts when bound to a Vulkan Loader that also exports identical symbols.
+For default compatability with the _Vulkan SDK_ loader environment, by default, **MoltenVK** hides
+static access to the _Vulkan_ API symbols (`vk*`), in favor of using the standard _Vulkan_ 
+function pointers retrieved using `vkGetInstanceProcAddr()` and `vkGetDeviceProcAddr()`.
 
-To do so, when building MoltenVK, set the build setting `MVK_HIDE_VULKAN_SYMBOLS=1`.
+If you are not using the _Vulkan_ loader, and wish to statically link to the _Vulkan_ API symbols, 
+you can optionally build **MoltenVK** with the _Vulkan_ API static call symbols exposed.
+
+To do so, when building **MoltenVK**, set the build setting `MVK_HIDE_VULKAN_SYMBOLS=0`.
 This build setting can be set in the `MoltenVK.xcodeproj` *Xcode* project,
 or it can be included in any of the `make` build commands. For example:
 
-	make MVK_HIDE_VULKAN_SYMBOLS=1
+	make MVK_HIDE_VULKAN_SYMBOLS=0
 or
 
-	make macos MVK_HIDE_VULKAN_SYMBOLS=1
