+## Compile-time requirements
+
+GLFW supports compilation on Visual C++ 2010 and later, MinGW and MinGW-w64,
+Clang on OS X and GCC and Clang on Linux and other Unix-like systems.  It will
+likely compile in other environments as well, but this is not regularly tested.
+
+See the [compilation guide](http://www.glfw.org/docs/latest/compile.html) for
+more information.
+
+
+## Run-time requirements
+
+GLFW supports Windows XP and later, OS X 10.7 Lion and later, and Linux and
+other Unix-like systems with the X Window System.
+
+Experimental implementations for the Wayland protocol and the Mir display
+server are available but not yet officially supported.
+
+See the [compatibility guide](http://www.glfw.org/docs/latest/compat.html)
