+// Dear ImGui: standalone example application for Win32 + OpenGL 3
+
+// 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
+
+// This is provided for completeness, however it is strongly recommended you use OpenGL with SDL or GLFW.
