How do you link a local repository to a remote one?

Short answer: After initializing a Git repo locally (git init), you can connect it to a remote repository (like one on GitHub) using: git remote add origin Then push your code: git push -u origin main Explanation: origin is just a nickname for the remote URL.

Explain a bit more

The -u flag links your local branch with the remote one so future pushes are easier (git push alone works after that). Real-world example: You create a local portfolio website and later decide to host it on GitHub. You connect your local repo to the remote one using git remote add origin so both stay in sync.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
