how to put two git repos in one project?

I had two of my apps set up as one webstorm project.  The project showed the two app root folders at the top.  Also the two git repos were synched.  My repos diverged, I have no idea how.  

I deleted my webstorm project and tried to recreate the setup.  I put the two folders in one project.  I told webstorm setup to link them but it didn't do anything.

I'm pretty sure I just forgot how to do this.  Can someone give me a hand?  I have no problem creating the project from scratch again.
