Submodules

Large projects can be split into smaller parts using submodules. A submodule contains the name, url and revision of another repository. To create a submodule in an existing git repository you need to add a link to another repository containing the files of the submodule.

Manage submodules

The current state of the submodules can be viewed with the Manage submodules function. All submodules are shown in the list on the left.

Add submodule	Add a new submodule to the repository
Synchronize	Synchronizes the remote URL configuration setting to the value specified in .gitmodules for the selected submodule.
Initialize	Initialize the selected submodules, i.e. register each submodule name and url found in .gitmodules into .git/config. The submodule will also be updated.
Update	Update the registered submodules, i.e. clone missing submodules and checkout the commit specified in the index of the containing repository.
Remove	Remove the submodule from the repository
