+##### Validation layers
+The example base class offers a constructor overload for enabling a default set of Vulkan validation layers (for debugging purposes). If you want to use this functionality, simple use the construtor override :
+```cpp
+VulkanExample() : VulkanExampleBase(true)
+{
+  ...
+}
+```
