How do you remove block/sections?

I’d like to remove or hide certain sections (ie. testimonials, employees, etc) from the demo site but I’m not able to figure it out. Thanks

Edit the page and you’ll see them listed there (I’m guessing you’ve imported the demo content). Simply delete the rows you don’t need.

Thank you! Yes, I’m starting with the demo content. I figured I must have been overlooking something obvious.
