$ git submodule add  (NOTE: Do not use local URLs here if you plan to publish your superproject!)

Pulling down the submodules is a two-step process. First run git submodule
init to add the submodule repository URLs to .git/config:
$ git submodule init
$ git submodule update


If you want to make a change within a submodule and you have a detached head, then you should create or checkout a branch, make your changes, publish the change within the submodule, and then update the superproject to reference the new commit:
