The steps you need to follow depend on the version of Publisher you are using.
Publisher 2010
Unfortunately, Microsoft has removed the website design features from Publisher 2010 which would help you create a new site. However, a site you created in Publisher 2007 can be edited, updated and uploaded through Publisher 2010.

There are only a few web publishing resources available on the Publisher 2007 “Help-and-How-To” site, but this article has everything you need.

Your Settings
Regardless of the version of Publisher you use, you will need these settings to publish your site via FTP:

Username: Your cPanel user name.
Password: Your current cPanel password.
Destination Folder/Directory: /public_html
