Main Widget Area On The Bottom

I’m a complete noob when it comes to all that is online so I’m you won’t use any big words.

I’d like a widget area on the bottom of my site (https://assetleader.ca/), just like the on on the side bar. And I haven’t a clue on how to do this. Ideally I’d like the contact info and the pages list to be on the bottom.

Thank you very much.
