+
+## Introduction
+
+GLFW is an 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.
+
+GLFW natively supports Windows, macOS and Linux and other Unix-like systems.
+Experimental implementations for the Wayland protocol and the Mir display server
+are available but not yet officially supported.                             
+
+GLFW is licensed under the [zlib/libpng
+license](http://www.glfw.org/license.html).
+
+The latest stable release is version 3.2.1.
+
+See the [downloads](http://www.glfw.org/download.html) page for details and
+files, or fetch the `latest` branch, which always points to the latest stable
+release.  Each release starting with 3.0 also has a corresponding [annotated
+tag](https://github.com/glfw/glfw/releases) with source and binary archives.
+The [version history](http://www.glfw.org/changelog.html) lists all user-visible
+changes for every release.
+
+This is a development branch for version 3.3, which is _not yet described_.
+Pre-release documentation is available [here](http://www.glfw.org/docs/3.3/).
+
+The `master` branch is the stable integration branch and _should_ always compile
+and run on all supported platforms, although details of newly added features may
+change until they have been included in a release.  New features and many bug
+fixes live in [other branches](https://github.com/glfw/glfw/branches/all) until
+they are stable enough to merge.
+
+If you are new to GLFW, you may find the
+[tutorial](http://www.glfw.org/docs/latest/quick.html) for GLFW 3 useful.  If
+you have used GLFW 2 in the past, there is a [transition
+guide](http://www.glfw.org/docs/latest/moving.html) for moving to the GLFW
+3 API.
+
+
+## Compiling GLFW
+
+GLFW itself requires only the headers and libraries for your window system.  It
+does not need the headers for any context creation API (WGL, GLX, EGL, NSGL,
+OSMesa) or rendering API (OpenGL, OpenGL ES, Vulkan) to enable support for them.
+
+GLFW supports compilation on Windows with Visual C++ 2010 and later, MinGW and
+MinGW-w64, on macOS with Clang and on Linux and other Unix-like systems with GCC
+and Clang.  It will likely compile in other environments as well, but this is
+not regularly tested.
+
+There are [pre-compiled Windows binaries](http://www.glfw.org/download.html)
+available for all supported compilers.
+
+See the [compilation guide](http://www.glfw.org/docs/latest/compile.html) for
+more information about how to compile GLFW yourself.
+
+
+## Using GLFW
+
+See the [documentation](http://www.glfw.org/docs/latest/) for tutorials, guides
+and the API reference.
+
+
+## Contributing to GLFW
+
+See the [contribution
+guide](https://github.com/glfw/glfw/blob/master/docs/CONTRIBUTING.md) for
+more information.
+
+
+## System requirements
+
+GLFW supports Windows XP and later and macOS 10.7 and later.  Linux and other
+Unix-like systems running the X Window System are supported even without
+a desktop environment or modern extensions, although some features require
+a running window or clipboard manager.  The OSMesa backend requires Mesa 6.3.
+
+See the [compatibility guide](http://www.glfw.org/docs/latest/compat.html)
+in the documentation for more information.
+
+
+## Dependencies
+
+GLFW itself depends only on the headers and libraries for your window system.
+
+The (experimental) Wayland backend also depends on the `extra-cmake-modules`
+package, which is used to generated Wayland protocol headers.
+
+The examples and test programs depend on a number of tiny libraries.  These are
+located in the `deps/` directory.
+
+ - [getopt\_port](https://github.com/kimgr/getopt_port/) for examples
+   with command-line options
+ - [TinyCThread](https://github.com/tinycthread/tinycthread) for threaded
+   examples
+ - An OpenGL 3.2 core loader generated by
+   [glad](https://github.com/Dav1dde/glad) for examples using modern OpenGL
+ - [linmath.h](https://github.com/datenwolf/linmath.h) for linear algebra in
+   examples
+ - [Nuklear](https://github.com/vurtun/nuklear) for test and example UI
+ - [stb\_image\_write](https://github.com/nothings/stb) for writing images to disk
+ - [Vulkan headers](https://www.khronos.org/registry/vulkan/) for Vulkan tests
+
+The Vulkan example additionally requires the Vulkan SDK to be installed, or it
+will not be included in the build.  On macOS you need to provide the path to the
+MoltenVK SDK manually as it has no standard installation location.
+
+The documentation is generated with [Doxygen](http://doxygen.org/) if CMake can
+find that tool.
+
+
+## Reporting bugs
+
+Bugs are reported to our [issue tracker](https://github.com/glfw/glfw/issues).
+Please check the [contribution
+guide](https://github.com/glfw/glfw/blob/master/docs/CONTRIBUTING.md) for
+information on what to include when reporting a bug.

+ *  @brief Functions related to accessing native handles.
+ *
+ *  **By using the native access functions you assert that you know what you're
+ *  doing and how to fix problems caused by using them.  If you don't, you
+ *  shouldn't be using them.**
+ *
+ *  Before the inclusion of @ref glfw3native.h, you may define zero or more
+ *  window system API macro and zero or more context creation API macros.
+ *
+ *  The chosen backends must match those the library was compiled for.  Failure
+ *  to do this will cause a link-time error.
+ *
+ *  The available window API macros are:
+ *  * `GLFW_EXPOSE_NATIVE_WIN32`
+ *  * `GLFW_EXPOSE_NATIVE_COCOA`
+ *  * `GLFW_EXPOSE_NATIVE_X11`
+ *  * `GLFW_EXPOSE_NATIVE_WAYLAND`
+ *  * `GLFW_EXPOSE_NATIVE_MIR`
+ *
+ *  The available context API macros are:
+ *  * `GLFW_EXPOSE_NATIVE_WGL`
+ *  * `GLFW_EXPOSE_NATIVE_NSGL`
+ *  * `GLFW_EXPOSE_NATIVE_GLX`
+ *  * `GLFW_EXPOSE_NATIVE_EGL`
+ *  * `GLFW_EXPOSE_NATIVE_OSMESA`
+ *
+ *  These macros select which of the native access functions that are declared
+ *  and which platform-specific headers to include.  It is then up your (by
+ *  definition platform-specific) code to handle which of these should be
+ *  defined.
