Replace Old Site with New, Using My Domain

I created a new website to replace my old, dated-looking site.  I pay for a domain name, www.singingboysbrewing.com and that is where the old site resides.  I want to move the new site to that domain name, please, and delete the old site entirely.  The new site is temporarily at http://www.sbbversion2.homesteadcloud.com/   Thanks in advance!
