-** Installing MinGW
+  There are two alternative to installing MinGW + MSYS: using the GUI
+  installer, called mingw-get, provided by the MinGW project, or
+  manual installation.  The next two sections describe each one of
+  these.
 
-  You will need to install the MinGW port of GCC and Binutils, and the
-  MinGW runtime and Windows API distributions, to compile Emacs.  You
-  can find these on the MinGW download/Base page:

-    https://sourceforge.net/projects/mingw/files/MinGW/Base/
-
-  In general, install the latest stable versions of the following
-  MinGW packages from that page: gcc, binutils, mingw-rt, w32api.  You
-  only need the 'bin' and the 'dll' tarballs of each of the above.
