How to add an existing local folder as a Git submodule?

Question

git

I read about git submodules, but I don't see how to do what I need. I have initialized the general local turnip of the site (Magento), in the subdirectory of the site I want to create a Magento module, for which there will be a separate turnip, while also local. What I see in the instructions is to add repositories from external sources:

git submodule add git://github.com/chneukirchen/rack.git rack

I just need to create a local submodule, to which I can then add an external origin, and the change history of which will be separate from the general change history of the site.
How to do it?

Answer 1

Try this
git submodule add file://path/to/chneukirchen/rack rack
