nfultz / How to add a submodule with shallow checkout and shallow clone

Created July 12, 2017 16:22 — forked from kouk/How to add a submodule with shallow checkout and shallow clone

.How to add a submodule with shallow checkout and shallow clone

	If you have a huge repository (in size and in history) and want to add a subfolder
	to your project as a submodule you can follow this example to save time and space
	using git's shallow clone and shallow checkout feature. It is a bit more complicated
	in this example because I assume that you want your submodule to track a non-default
	branch, called `mybranch`, instead of the `master` branch. Things could probably get
	a lot simpler when using the default branch. After following the commands in these
	examples you can use `git submodule update` and `git submodule update --remote` as normal.
