Empty Git submodule folder when repo cloned

Question

I have one repo hosted at https://github.com/aikiframework/json . On my local copy, I added a submodule using the command

git submodule add git@github.com:jcubic         


        

Answer 1

OK I found it, needed to add --recursive when cloning the repo.

So the clone command ends up as:

git clone https://github.com/aikiframework/json.git --recursive
