The description of your project is actually tied into the Pages system.
Thus, to edit the description of your project, you merely have to edit the Main page of your project.
Click on the page on your project, and choose Page Actions -> Edit Page.
If you'd like to add a description that isn't English, what you should do is create a page (Project Actions -> Create Page) with the name Main and the language of your choice.
