+### Using GNU Make ###
+The make/ directory contains a Makefile that you can use to build
+Google Test on systems where GNU make is available (e.g. Linux, Mac OS
+X, and Cygwin).  It doesn't try to build Google Test's own tests.
+Instead, it just builds the Google Test library and a sample test.
+You can use it as a starting point for your own Makefile.
+
+If the default settings are correct for your environment, the
+following commands should succeed:
+
+  $ cd ${SRCDIR}/make
+  $ make
+  $ ./sample1_unittest
+
+If you see errors, try to tweak the contents of make/Makefile to make
+them go away.  There are instructions in make/Makefile on how to do
+it.

 ### Using Your Own Build System ###
 If none of the build solutions we provide works for you, or if you
 prefer your own build system, you just need to compile

+# A sample Makefile for building Google Test and using it in user
+# tests.  Please tweak it to suit your environment and project.  You
+# may want to move it to your project's root directory.
+#
+# SYNOPSIS:
+#
+#   make [all]  - makes everything.
+#   make TARGET - makes the given target.
+#   make clean  - removes all files generated by make.
+
+# Please tweak the following variable definitions as needed by your
+# project, except GTEST_HEADERS, which you can use in your own targets
+# but shouldn't modify.
+
+# Points to the root of Google Test, relative to where this file is.
+# Remember to tweak this if you move this file.
