Posts order

First of all, thank you for this great plugin! I love it.

I am currently using it on a new website where I will display Posts for a specific (news) Category on a custom Page : http://www.lezilus.eu/actualite/

Is it possible to set the order the Posts appear, so the newest one shows first (instead of having the Posts to show randomly)?
Maybe by ordering it by date?
If yes, please let me know precisely what I should do.
Thanks
