How can existing comps be made into a webflow site?

Webflow newbie here. the design ideas were made using “Old Thinking.” In other words, make comps of a web design (in Illustrator, Fireworks, Photoshop, Sketch, etc.) & then use Dreamweaver or the likes to make the design live in code-land.

Since it’s unlikely that I’m the first virgin to show up here, thinking Dressing Room instead of Sacrifice, there must be an article or tutorial to set me straight. Can someone please send an appropriate link or two?
