+// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
+// If you use this binding you'll need to call 5 functions: ImGui_ImplXXXX_Init(), ImGui_ImplXXX_CreateFontsTexture(), ImGui_ImplXXXX_NewFrame(), ImGui_ImplXXXX_Render() and ImGui_ImplXXXX_Shutdown().
+// If you are new to ImGui, see examples/README.txt and documentation at the top of imgui.cpp.
