WebMatrix gives: Description is missing

Topics: Customizing Orchard

Hi, I have finished a website, but before deploying I decided to make a report inside WebMatrix.
I got a warning message, saying: The description is missing and as far i can see, it is for all pages I made and you should have a meta tag added.
At an Microsoft site i have read that this message could not be corrected by WebMatrix, but that Orchard should have an administratieve control panel to do so.
Should I have a Robots.txt file added to the ROOT of Orchard?
I hope that someone can tell me how to correct this, or that it is no problem at all.
thanks in advance for any answer
