+Installing Fortune Plugin
+=========================
+Simply untar the file in the plugins directory, and make sure it is
+in its own directory, and that the name of the directory is the name
+of the plugin.  Example below uses "fortune" as the name of the 
+directory:
+
+  $ cd plugins
+  $ tar -zxvf /usr/archives/fortune_plugin.tar.gz
+
+You may have to edit plugins/fortune/setup.php and change the location
+of fortune on your system. Simply modify the $fortune_location variable
+This script was written on RedHat 6.2 as such fortune is expected in 
+/usr/games/fortune also if safe mode is enabled your going to have to 
+copy fortune into your safe_mode bin directory.
+
+Then go to your config directory and run conf.pl.  Choose option
+8 and add the plugin (+).  Save and exit, then that should be all
+if the plugin was made correctly.  :)
+
+  $ cd ../config
+  $ ./conf.pl
