Is there any way to smooth the scrolling down on my website?

Hello! I've been searching for hours now to try and create the same scrolling effect use on this website:

I want that "easing" effect that just makes it feel so much smoother than regular scrolling. I just don't know where to find the answers so I'm trying here!

Thanks in advance!
