This information is technical in nature but has some importance for general users.
As this kind of clone have a separate gitdir, you will have a surprise if you
copy past the worktree as the gitdir will not come together.
I have done it and as the doc say nothing about that it take me some time to
understand what happened. And why this repository behave differently than others.

May be I can rephrase like this :

*NOTE*: when 'submodule add' or 'submodule update' commands clone a missing
submodule, the $GIT_DIR of the submodule containing the metadata is placed
outside of its working directory in the $GIT_DIR/modules of the current
repository. Those submodule can not directly be copied or move.
You need to use 'git clone'.
