Making ONLY most recent post display on front-page.php

I am having trouble figuring out how to make sure that only my most recent post is displayed on the front page of my front-page.php file, since I have some custom post types and would like for my most recent post to just display below my most recent of the custom post type.

Sorry if this makes no sense, basically I just want to know what to add to the wordpress loop to make sure that it only gives me the most recent post, and no others.
