+<p>Vulkan is a low-overhead, cross-platform API for high-performance 3D graphics.
+Like OpenGL ES, Vulkan provides tools for creating high-quality, real-time
+graphics in applications. Vulkan advantages include reductions in CPU overhead
+and support for the SPIR-V Binary Intermediate language.</p>
