Check out from version control (git) with submodules

Hi, I've just ported a large project to IDEA 13.0.1 on Linux and it's working wonderfully, thank you!

I am writing instructions for team members on how to clone our git repository. I'm using the initial dialog and the option Check out from Version Control > Git

Everything works fine except that we have a git submodule which points to a github project and the clone did not recursively check this out. How do I do a recursive check out from git version control with submodules?

Thanks
