This tutorial aims to show you how to make a folder in google doc public to the web. Please be reminded that, although, in theory, people do not need to log in to see the folder and files that are made public to the web. Yet, for "shared folders", at this point, and, after I tested using Firefox, Internet Explorer and Chrome, if I don't log in to a google account, all that I see a a white page when loading the urls. Thus, in order for people to see the folders made public to the web, you need to tell them to log in to their google account. However, there is no problem with shared files.
