Birds-eye-view to bring all the steps together

[ghost]

The narrative arc of this guide is:

• Given a Dat URL, how do I download the files in it, and
• Given some files, how do I share them with others using Dat

Currently all the pieces are there but I want to try adding a section that recaps and brings everything together. Maybe even using a mega-figure that combines all the steps with a zoomed-out view.
