Category as URI segment?

[eluser]Unknown[/eluser]
Hi,

I'm fairly new to CI ( but loving it so far ) and i made this simple site which can show all posts, or a specific post if you click on it.

Now everything is working but when u go to a single post the url looks like this

Code:

site/article/article-name ...

is it possible to have the category name in the uri instead of 'article'

Code:

site/updates/article-name

( where updates is the name of a category )
