How to add nested git repositories?

Question

vim

Hello.
Recently I wanted to start a dotfiles repository to store vim settings. I use Vundle to manage plugins. Most plugins are installed from GitHub and are git repositories, just like Vundle itself. I moved everything to the dotfiles folder and created the repository there in the usual way:

git init
git remote add origin ...
git add .
git commit -m 'Initial commit'
git push origin master

And I found that the plugins were not committed. Is there a way to add them?
Thanks in advance.
