@ -9,34 +9,28 @@ 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. On
Linux both Wayland and X11 are supported.
GLFW is written primarily in C99, with parts of macOS support being written in
Objective-C.
GLFW supports Windows, macOS and Linux, and also works on many other Unix-like

You can [download](https://www.glfw.org/download.html) the latest stable release

a corresponding [annotated tag](https://github.com/glfw/glfw/releases) with
source and binary archives.

## Compiling GLFW
GLFW is written primarily in C99, with parts of macOS support being written in
Objective-C. GLFW itself requires only the headers and libraries for your OS
and window system. It does not need any additional headers for context creation
APIs (WGL, GLX, EGL, NSGL, OSMesa) or rendering APIs (OpenGL, OpenGL ES, Vulkan)
to enable support for them.
GLFW supports compilation on Windows with Visual C++ (2013 and later) 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 binaries](https://www.glfw.org/download.html) available
for all supported compilers on Windows and macOS.
See the [compilation guide](https://www.glfw.org/docs/latest/compile.html) for
more information about how to compile GLFW yourself.
## Using GLFW
See the [documentation](https://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 7 and later and macOS 10.11 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.
GLFW supports Windows 7 and later and macOS 10.11 and later. On GNOME Wayland,
window decorations will be very basic unless the
[libdecor](https://gitlab.freedesktop.org/libdecor/libdecor) package is
installed. Linux and other Unix-like systems running X11 are supported even
without a desktop environment or modern extensions, although some features
require a clipboard manager or a modern window manager.

OS and window system.

The `master` branch is the stable integration branch and _should_ always compile
and run on all supported platforms. Details of a newly added feature,
including the public API, may change until it has been included in a release.
The `latest` branch is equivalent to the [highest numbered](https://semver.org/)
release, although it may not always point to the same commit as the tag for that
release.
The `ci` branch is used to trigger continuous integration jobs for code under
testing and should never be relied on for any purpose.
