This document discusses setting up a WordPress multisite network. It provides instructions for enabling multisite mode by adding definitions to the wp-config.php file. Additional steps include creating a blogs.dir folder for uploaded files, modifying .htaccess, and refreshing the dashboard. Once complete, the WordPress installation can support multiple sites using subdomains or subdirectories, with shared plugins, themes and menus across all sites. Child themes allow customizing parent themes, while custom post types extend functionality.

5. Other Setup Steps
1. Create a blogs.dir directory under /wp-content/
This directory is used to stored uploaded media for your additional sites and
must be writable by the web server. They should be CHOWNed and
CHMODed the same as your wp-content folder.
2. Add the extra lines provided to your wp-config.php file
These lines are dynamically generated for you based on your configuration.
Put these lines right under the WP_ALLOW_MULTISITE line, mostly for
readability.
3. Replace the content of your .htaccess file with the following
(If there isn't one, then create it.)
These lines are dynamically generated for you based on your configuration.
4. Once the above steps are completed and the new wp-config.php & .htaccess
files are saved, click "Return to Dashboard" to refresh your dashboard.
