git push origin main4.3 Pulling Changes
To update your local repository with changes from the remote repository, use:
git pull origin main5. Best Practices
Always commit your changes locally before pushing to the remote repository to maintain a clean history.
- Use meaningful commit messages.

- Use branches to manage features or fixes separately.
- Collaborate with team members effectively by using pull requests.
6. FAQ
What is the difference between git pull and git fetch?
git pull updates your local repository with changes from the remote repository and merges them, while git fetch only updates the local copy of the remote repository without merging.
How do I resolve merge conflicts?
To resolve merge conflicts, open the conflicting file(s), find the conflict markers, and manually edit the lines to resolve the conflict. After resolving, add the files and commit the changes.
Can I delete a remote repository?
Yes, you can delete a remote repository through the hosting service's interface (e.g., GitHub or GitLab), but be cautious as this action is irreversible.
