+A simple Object Oriented C++ OpenGL wrapper library inspired by [Processing](https://processing.org).
+
+## Features
+* orthographic and perspective projection
+* window handling
+* complete matrix handling
+* 2D textures
+* instancing
+
+Check [examples](https://github.com/flightcoded/fly-graphics/tree/master/examples).
+
+## Dependencies
+* [GLAD](https://glad.dav1d.de) (configured for OpenGL 3.3 Core)
+* [GLFW](https://www.glfw.org)
+* [GLM](https://github.com/g-truc/glm)
+* [stb_image](https://github.com/nothings/stb/blob/master/stb_image.h)
+
+There is a complete Visual Studio project with all dependencies linked and included under [releases](https://github.com/flightcoded/fly-graphics/releases). Feel free to create an issue or contact me should you find an error or just want to.
