How can I add wordpress to my .com website? The site is mainly geared towards sports commentary, so wordpress is kind of a necessity. Thanks!
Sounds like your site is live and not WordPress, right? In that case you can add the WordPress install in a subdirectory. Example: yoursite.com/blog or yoursite.com/commentary.
How you would accomplish this depends on which hosting platform you are on. GoDaddy has help articles on subdomains that you may find helpful.
