Combine the submodule flow to manage an embedded repo.
Summary: Submodule workflow
A submodule lets you use an independent Git repository inside another project. Use git submodule add with a repository URL and target directory to add it. The parent repository stores a reference to a specific submodule commit.
git submodule add https://github.com/example/shared.git vendor/sharedAfter cloning the project, use git submodule update --init --recursive to prepare submodules and nested submodules.
Practice Complete the submodule workflow
Add https://github.com/example/chart-kit.git as a submodule at vendor/chart-kit. Then initialize and update all submodules in the parent project, including nested submodules.

Questions and answers
Review the lesson questions together with their answers. To test yourself, solve the lesson interactively.
1 A teammate who cloned the parent project needs to prepare nested submodules as well. Which command performs the required initialization and update operations?
- git submodule status --recursive
- git submodule update --init --recursive Correct answer
- git submodule add --recursive
- git submodule reset --recursive
Explanation: update --init --recursive initializes submodules and updates nested submodules as well.
