-==================
+Installation methods
+====================
 
-Stow is a Perl script.  You must have Perl 5.005 or later in order for 
-it to run.
+Stow can either be installed via the standard GNU Autotools procedure
+(./configure, make install) or since 2.1.0, via CPAN-style via
+Module::Build.
 
-The steps in building stow are:
+Advantages of the Autotools approach:
 
-1.  `cd' to the directory containing the source code (and this file)
-    and type `./configure' to configure stow for your system.  This
+  - It's arguably more flexible.
+
+  - It will install the documentation in Info, HTML, man, and PDF
+    formats.
+
+Advantages of the Module::Build approach:
+
+  - It's more in keeping with the standard way to distribute CPAN
+    modules.
+
+  - It performs dependency checking to ensure you have the necessary
+    Perl modules installed.

+1.  `cd' to the directory containing the source code (and this file).
+
+2.  If you are building from an official GNU release tarball, type
+    `./configure && make' to configure stow for your system.  If you
+    are building from a CPAN tarball, this step can be skipped.
+
+3.  Type `perl Build.PL'.
+
+4.  Type `./Build install' to install the various files.  As noted
+    above, this installs fewer files than the Autotools installation.
