Since the content is stored in the database, there is no way to get the same content without using a backup of the old database and restore it to a new database.
Another option is using Sitefinity built in tool under Administration >> Tools section. It exports all data from pages in the Pages section, data from the following modules: Generic Content, News, Lists,
Blogs. Most probably your friend has told you about this approach. During installation you can select the exported project as "template"
I hope this helps.
