Capistrano Help

I want to set up Capistrano. I am reading . It says "…be sure to append /current/public, instead of the default…"
The form has a suggestion there and you’re supposed to change it, but is it supposed to be “{suggestion}/current/public”, or just “/current/public”?

Also, it says later it says " After DNS allows access to your folder…" why would dns allow you to get to the /current/pubic folder? Wouldn’t that be the root (so you would see just, not with the folders)?
