+### Presentattion
+**vke.net** (_vulkan engine for .net_) a vulkan abstraction layer writen in c# composed of high level classes encapsulating [vulkan](https://www.khronos.org/vulkan/) objects and commands with `IDispose` model and **reference counting**. [GLFW](https://www.glfw.org/)  handles the windowing system.
 
 Vke use autogenerated [vk.net](https://github.com/jpbruyere/vk.net) library for low level binding to vulkan.

+vke is in early development stage.

 ### Requirements
 - [GLFW](https://www.glfw.org/) if you use the `VkWindow` class.
 - If you want to use `jpg`, `jpeg`, `png` image [libstb](https://github.com/nothings/stb) (on debian install **libstb-dev**). Note that `ktx` image loading has no dependencies.
