Once you have one or a few submodules added, you will notice a new file named .gitmodules inside your repository. This is a configuration file which holds all information about what you’ve pulled from where. The content of .gitmodules should look something like this :
[submodule "requests"]
path = requests
url = https://github.com/psf/requests.gitThe file may contain more entries as you add more submodules.
You should keep in mind that gitmodules is version-controlled along with the rest of your repository. Anyone who clone/fork from you should be able to access your submodules as well.
