How can I specify a branch/tag when adding a Git submodule?

Question

How does git submodule add -b work?

After adding a submodule with a specific branch, a new cloned repository (after git submodule update --init

Answer 1

An example of how I use Git submodules.

1. Create a new repository
2. Then clone another repository as a submodule
3. Then we have that submodule use a tag called V3.1.2
4. And then we commit.

And that looks a little bit like this:

git init 
vi README
git add README
git commit 
git submodule add git://github.com/XXXXX/xxx.yyyy.git stm32_std_lib
git status

git submodule init
git submodule update

cd stm32_std_lib/
git reset --hard V3.1.2 
cd ..
git commit -a

git submodule status 

Maybe it helps (even though I use a tag and not a branch)?
