From what I can tell, you can basically take your USB drive of "websites" to your friend, and sync it with their local folder of "websites", and now you both have the most up to date versions of your combined group of "websites". (if your usb has Website A version 1 and Website B version 2, and you sync with someone who has Website A version 2 and Website C version 1, you'd both end up with Website A V2, Website B V2 and Website C V1)
The application also apparently has protections in place so you can't just create an updated version of someone else's website and distribute it the same way to impersonate them
I belive it also goes into the larger Wormblossom Willow project where there will be an online component, so that you can distribute stuff either online or via USB, building a sensorship-resistant protocol that works both online and offline.

I think with the authoritarian and dystopian crackdown on parts of the Internet where people express opinions, this will be a key driver. It reminds me of Cuba's "El Paquete" system. I find it ironic that a system developed to circumvent state oppression should now find a potential use case in our allegedly civilised countries.
