 ## 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) 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/.github/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.
