+* For the impatient
+
+  Here are the concise instructions for configuring and building the
+  native Win32 binary of Emacs on Windows, for those who want to skip
+  the complex explanations and ``just do it'':
+
+  1. Change to the `nt' directory (the directory of this file):
+
+       cd nt
+
+  2. Run configure.bat.  From the COMMAND.COM/CMD.EXE command prompt:
+
+       configure
+
+     from a Unixy shell prompt:
+
+       cmd /c configure.bat
+     or
+       command.com /c configure.bat
+
+  3. Run the Make utility suitable for your environment.  If you build
+     with the Microsoft's Visual C compiler:
+
+       nmake
+
+     For the development environments based on GNU GCC (MinGW, MSYS,
+     Cygwin), depending on how Make is called, it could be:
+
+       make
+     or
+       gnumake
+     or
+       gmake
+
+     (If you are building from CVS, say "make bootstrap" or "nmake
+     bootstrap" instead.)
+
+  4. Generate the Info manuals (only if you are building out of CVS):
+
+     make info
+
+     (change "make" to "nmake" if you use MSVC).
+
+  5. Install the produced binaries:
+
+     make install
+
+  That's it!
