Git Submodules and Advanced Repository Structure

📦 What are Git Submodules?

🧩 Submodule = embedding one Git repository inside another

✅ Useful when your project depends on a specific version of another library

🔗 The submodule is tracked at a specific commit hash — not a branch

🏢 Common in large enterprise monorepos and complex project architectures

➕ Add a Submodule on 🪟 Windows 11

⊞Windows 11 Command Prompt (cmd.exe)

git submodule add https://github.com/nextsemacademy/ui-components.git src/ui-components

⊞Windows 11 Command Prompt Execution OutputWindows 11 Verified
