+* Installing Git for Windows
+
+  Skip this section if you already have Git installed and configured,
+  or if you are building from the release tarball, not from the
+  development repository.
+
+  Git for Windows is available from this download page:
+
+    https://github.com/git-for-windows/git/releases
+
+  That page offers both 32-bit and 64-bit installations; pick the one
+  suitable for your OS.  In general, we recommend to install a 64-bit
+  Git if you have a 64-bit Windows system; the 32-bit Git will run on
+  64-bit Windows just fine, but might run into memory problems where
+  the 64-bit Git won't.
+
+  During Git installation, be sure to select the "Checkout as-is,
+  commit as-is" option from the "Configure line ending conversions"
+  dialog.  Otherwise, Git will convert text files to DOS-style CRLF
+  end-of-line (EOL) format, which will cause subtle problems when
+  building Emacs, because MSYS tools (see below) used to build Emacs
+  use binary file I/O that preserves the CR characters that get in the
+  way of some text-processing tools, like 'makeinfo' and the commands
+  invoked by the autogen.sh script.
+
+  If you already have Git installed and configured with some other EOL
+  conversion option, you will need to reconfigure it, removing the
+  following variables from all of your .gitconfig files:
+
+    core.eol
+    core.safecrlf
+    core.autocrlf
+
+  If you cloned the Emacs directory before changing these config
+  variables, you will have to delete the repository and re-clone it
+  after the change.
+
+  The instructions for cloning the Emacs repository can be found on
+  the Emacs's Savannah project page:
+
+    https://savannah.gnu.org/projects/emacs
