+* Main Data Structures

+** Instance
+*** The most important part
+
+- Purpose :: Serves as the connection between the application and Vulkan itself.
+- Usage :: Call src_c++{vk::CreateInstance} and pass in an src_c++{InstanceCreateInfo} object
+  - Note :: Anything starting with src_c++{p} / src_c++{pp} is a pointer / pointer to a pointer, respectively.
