Wordpress preinstalled

I just signed up with DH and got an email from DreamHost Installer Robot
with the subject line Success installing WordPress on your site! With links to set up admin user ect. I am sort of confused because I didn’t install Wordpress by using the one click installer or manually. Is this something that is just automatic when you register for hosting ?

I do plan to install wordpress in subfolder when the domain propagates. I was planning on using the main index as a splash page.

Thanks for any help


We install WordPress automatically if you sign up with certain WP-specific promo codes or referrers, or if you sign up after clicking through to our web site from http://wordpress.org/hosting.
