+// dear imgui: Platform Backend for Raylib
+// (Info: Raylib is a cross-platform general purpose library for handling windows, inputs, graphics context creation, etc. using OpenGL)
+// This is is the low level ImGui backend for raylib, a higher level API that matches the raylib API can be found in rlImGui.h
+
+// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
+// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
+// Learn about Dear ImGui:
+// - FAQ                  https://dearimgui.com/faq
+// - Getting Started      https://dearimgui.com/getting-started
+// - Documentation        https://dearimgui.com/docs (same as your local docs/ folder).
+// - Introduction, links and more at the top of imgui.cpp
