Okay so I have two repo name X and Y. I have the same structure for both x->internal, product and y->internal, product. I want to use x’s product in y and I would like to know what would happen if I created a release?

I added the submodule, but it has all the folders in it including the internal. I removed It and tried using a tag but won’t helped at all. Also where I can read more about the submodules other than official documents.
