git

To initialize a Git repository, use the git init command in your project directory, then add a remote origin using git remote add to link your local repository to a remote server for pushing and pulling code.

Merge conflicts in Git are resolved by identifying the conflicting sections in your files, manually editing them to keep the desired changes, staging the resolved files with git add, and completing the merge with a commit.

Yes, you can undo a recent commit in version control using commands like git reset or git revert, allowing you to unstage changes or create a new commit that undoes the previous one while preserving your repository history.

Manage branching and merging by creating independent branches with git branch, switching between them, and integrating changes back into the main branch using git merge to ensure smooth collaborative development.

You need to configure a .gitignore file when setting up your repository to specify intentionally untracked files, preventing build artifacts, temporary files, and sensitive data from being committed to version control.

Git requires user identity configuration before committing so that every commit is properly attributed to the correct author, ensuring traceability and accountability across collaborative development workflows.
