### Internal links
It's easy to link between slides. The first example below targets the index of another slide whereas the second targets a slide with an ID attribute (```<section id="'"some-slide">```):
```html
<a href="#/2/2">Link</a>
<a href="#/some-slide">Link</a>
```
## PDF Export
Presentations can be exported to PDF via a special print stylesheet. This feature requires that you use [Google Chrome](http://google.com/chrome).
