If you’re working with a large project, then you must have come across the concept of Git Submodules.

In simple terms, Git submodule is a project packaged within an existing project.

In this article, we will explain how we can add a Git submodule to the main repository from your local machine.

But before we start, we’ll need to setup SSH in our machine. Here’s a link for your help https://cloudservicestutorial.com/connecting-to-github-with-ssh/.

In order to add a Git submodule:

First, go to the main repository in your system. There, you’ll find a folder named “app_src“. Open “git bash” in the target directory.

Use this command: $ git submodule add <your_sub_project_name>

Next, Open GitHub desktop and “commit” and then “push” the changes.

Now, you’ll be able to see a folder with the name of your submodule under /app_src, and a file named “.gitsubmodules” is created in your Git main repository. This file will contain the list of repositories that are packaged under your main module.
