Description: Adding a submodule in Git is a command that allows you to include an external repository within another repository, creating a dependency relationship between the two. This command is particularly useful for managing projects that require libraries or code modules developed independently. By adding a submodule, you can maintain version control of each component separately, facilitating collaboration and integration of different parts of a project. The submodule is stored in a specific folder within the main repository, and its state is managed through references to specific commits of the external repository. This ensures that when cloning the main repository, you can access the exact version of the submodule that was used in development, avoiding compatibility issues and ensuring project stability. Additionally, the use of submodules allows developers to work on different parts of a project without interfering with others’ work, promoting a more modular and organized structure in software development.
