+4. INSTALLING MODULES AND THEMES
+
+   Drupal ships with a number of default modules and themes in the
+   'modules' and 'themes' directories, respectively. You can download
+   additional modules and themes from http://drupal.org/project. 
+
+   The recommended place to put new modules and themes is in the 'sites' 
+   directory. To make a module or theme available to all sites, simply 
+   place it under the sites/all/modules directory or sites/all/themes 
+   directory. To make it available to only one site, place it in the 
+   sites/sub.example.com/modules or sites/sub.example.com/themes directory.
+
+   For example, to make module_a and theme_a available to all sites, but
+   module_b and theme_b available only to sub.example.com, the setup
+   would look like this:
+
+     sites/all/:
+       themes/theme_a
+       modules/module_a
      sites/sub.example.com/:
        settings.php
-       themes/custom_theme
-       modules/custom_module
+       themes/theme_b
+       modules/module_b
 
    NOTE: for more information about multiple virtual hosts or the
-   configuration settings, consult the Drupal handbook at drupal.org.
