How to install a landing page template into WordPress site in Dreamhost

Hello,

I am a newbie to WordPress but I am pressed by a deadline to create a landing page on a fully hosted site on Dreamhost.

I downloaded this landing page template: https://themeforest.net/item/landlr-the-allinone-landing-page-wordpress/6952895

I extracted the download but found no installation instructions. I am completely lost here, not knowing what to do.

Can anyone help me through this? I have only less than 24 hours to finish it by the deadline. Thank you SOOO much in advance!
