In our presentation definition file we named our first slide slides/foo/intro.xml, so create this file with your favourite text editor. The path is relative to the presentation directory configured in your config.php file. Here is a simple example that just has a slide title and a blurb of text with a title.

<slide title="This is an Example Slide">
  <blurb title="Blurb Title">
Here is a sample paragraph.  
Next we will look at the markup tags available.
  </blurb>
</slide>

Don't worry about indenting the tags if you don't feel like it. It is not required.

To see what this looks like, go to the next slide.
