Add a Submodule

Objective

Include repository B as a submodule in repository A, such that the submodule always points to the latest version of the main branch of repository B.

Steps

1. Navigate to Repository A

Go to your repository A using the command line:

cd /path/to/your/repo-A

2. Add Repository B as a Submodule

Add repository B as a submodule at a specific location within repository A. Replace URL-of-repo-B with the URL of your repository B, and path/to/submodule with the desired directory for the submodule:

git submodule add -b main URL-of-repo-B path/to/submodule

3. Initialize and Update the Submodule

Initialize and update the submodule to clone the latest version of the main branch:

git submodule update --init --remote

5. Commit the Changes

Save the changes in your repository A:

git add .gitmodules path/to/submodule
git commit -m "Add repo-B submodule and configure to track main branch"

6. Update the Submodule to Get the Latest Changes

To update the submodule to the latest version of the main branch at any time, use:

git submodule update --remote
