Query on wordpress automatic plugin

Hello folks,

I would like to add the title and a few words of description from the source to my site. How do i achieve this using this plugin?

I know it can be done using feed as is... but it contains only few words... I need like 2 to 3 lines needs to be imported from them and will give as read more to the source.

Basically I am trying to avoid copyrighting as well by importing full content.
