Introductory text in list pages

I'm not sure how to do the following in Drupal:

I have a list page (which basically displays a list of all the node of a specific content type). I would like, right before that list, to have an Introductory text. How can I achieve this?

It would look like this:

####################
[Page title]

[Introduction text, i.e "Hello! This is the section where you can read stories of other people."]

[Node list begins here]
[1st node teaser]
[2nd node teaser]
[3rd node teaser]

First page Previous page 1 2 Next page Last page
####################

How to achieve this?
