WordPress blog feed on non-WP website

Is there a well documented process for getting some kind of feed of the latest posts (eg: latest 5 posts) so i can use that to output into a non-WP site?

Client has a corporate production site, and a blog in WP.
I need to add the latest posts to the homepage of the corporate site.

Hoping to be able to grab a feed or something and render that to the non-WP site so it is dynamically updated.

Any pointers?

Thanks
