Importing Existing Node/Express Project

I know you can create a node/express project from IntelliJ, but I haven't been able to import an existing one as an IntelliJ project.  Is there a way to do this?  I've tried creating a new node/express project using my existing sources, but when I do that it overwrites some files and I have to use use git reset to revert those changes.  I'm hoping there's a better way of doing this.  Thanks.

Edit: I'm using IntelliJ IDEA 12
