Question: Multisite, local (XAMPP) install

[donnahaynes]

Hi,
Please accept my apologies in advance if this has been covered in previous questions. I have attempted other fixes listed here but am still having issues getting WP Multisite to work.
I have an existing site set up with this WordPress skeleton in XAMPP. I would like to change this existing site to use multisite. I am getting conflicting messages about whether to use the sub-directory or sub-domain option, what additional code to include in my .htaccess file to make multisite work with WP Skeleton, and whether or not to have the trailing /wp in the site address setting.
I have attempted changing the existing site, and also creating a blank site with WP Skeleton. Both times, once I have made the config changes to wp-config.php and .htaccess, logged out, cleared my cookies and browser cache, and logged back in, I do not see any change in my WP dashboard that indicates I am now running a Multisite site.
Tell me if I'm asking too much, but is it possible to have a guide to set up multisite with the skeleton?
Thanks in advance :)
