-@section main_intro Introduction
-
-GLFW is a free, Open Source, multi-platform library for OpenGL, OpenGL ES and
-Vulkan application development.  It provides a simple, platform-independent API
-for creating windows, contexts and surfaces, reading input, handling events, etc.
-
-@ref news_34 list new features, caveats and deprecations.
-
-@ref quick_guide is a guide for users new to GLFW.  It takes you through how to
-write a small but complete program.
-
-There are guides for each section of the API:
-
- - @ref intro_guide – initialization, error handling and high-level design
- - @ref window_guide – creating and working with windows and framebuffers
- - @ref context_guide – working with OpenGL and OpenGL ES contexts
- - @ref vulkan_guide - working with Vulkan objects and extensions
- - @ref monitor_guide – enumerating and working with monitors and video modes
- - @ref input_guide – receiving events, polling and processing input
-
-Once you have written a program, see @ref compile_guide and @ref build_guide.
-
-The [reference documentation](modules.html) provides more detailed information
-about specific functions.
-
-@ref moving_guide explains what has changed and how to update existing code to
-use the new API.
-
-There is a section on @ref guarantees_limitations for pointer lifetimes,
-reentrancy, thread safety, event order and backward and forward compatibility.
-
-The [FAQ](https://www.glfw.org/faq.html) answers many common questions about the
-design, implementation and use of GLFW.
-
-Finally, @ref compat_guide explains what APIs, standards and protocols GLFW uses
-and what happens when they are not present on a given machine.
-
-This documentation was generated with Doxygen.  The sources for it are available
-in both the [source distribution](https://www.glfw.org/download.html) and
-[GitHub repository](https://github.com/glfw/glfw).
