Is it all that different from hosting on S3 or Firebase or GitHub pages?
Basically, if you have a repository with your Jekyll (or whatever) site, just add it to Netlify and that's it. It's served, and will automatically update when you push.

That's funny, but as someone who still does not use drop box, NFS shares seem a lot easier to me than setting up drop box. I think I tried drop box once but I found it more onerous to log in than to type mount /mnt/nfs , so.... I guess I'm not the target market (and that's okay!).
