Most Wordpress blogs have RSS enabled by default, so you don't need to do anything special.

For example, if you have a Wordpress blog at http://mywordpressblog.comthen your Wordpress RSS URL is probably at http://mywordpressblog.com/feed/rss/

However, if you have a smart RSS reader, then you don't need to know your RSS URL. You can just add it directly via the main URL.
