customize footer/add widgets

https://www.thenewsdispatch.net

I’d like to add some widgets to the footer of this site. I’ve already seen some threads providing code to add onto a child theme and create the widgets, but none of the code worked with my site, so I figured I’d make a thread with my own site url..
I also talked to the theme creator and he said he wouldn’t be able to get back to me for a few weeks, and basically told me to come here for code that would add the widgets to the footer.
Thank you for your time and help
