-<li>If you want your Makefiles to be configured by the <tt>configure</tt>
-script, or if you want to support multiple object directories, add your
-Makefiles to the <tt>configure</tt> script by adding them into the
-<tt>autoconf/configure.ac</tt> file. The macro <tt>AC_CONFIG_MAKEFILE</tt> will
-copy a file, unmodified, from the source directory to the object directory.</li>
+<li>If you want your project to be configured with the <tt>configure</tt> script
+then you need to edit <tt>autoconf/configure.ac</tt> as follows:
+ <ul>
+ <li><b>AC_INIT</b>. Place the name of your project, its version number and
+ a contact email address for your project as the arguments to this macro</li>
+ <li><b>AC_CONFIG_AUX_DIR</b>. If your project isn't in the
+ <tt>llvm/projects</tt> directory then you might need to adjust this so that
+ it specifies a relative path to the <tt>llvm/autoconf</tt> directory.</li>
+ <li><b>LLVM_CONFIG_PROJECT</b>. Just leave this alone.</li>
+ <li><b>AC_CONFIG_SRCDIR</b>. Specify a path to a file name that identifies
+ your project; or just leave it at <tt>Makefile.common.in</tt></li>
+ <li><b>AC_CONFIG_FILES</b>. Do not change.</li>
+ <li><b>AC_CONFIG_MAKEFILE</b>. Use one of these macros for each Makefile
+ that your project uses. This macro arranges for your makefiles to be copied
+ from the source directory, unmodified, to the build directory.</li>
+ </ul>
