GIT & GITHUB MASTERY

From Your First Commit to Professional Version Control & Team Collaboration

This comprehensive handbook begins with version control fundamentals and guides you through everyday Git commands, commits, branches, merging, conflict resolution, remote repositories, and GitHub authentication. You’ll then progress to professional collaboration using pull requests, code reviews, forks, issues, projects, organizations, and team workflows. The book also covers essential advanced topics—including rebase, cherry-pick, stash, tags, releases, bisect, reflog, Git internals, .gitignore, Git LFS, and safe recovery techniques. You’ll explore popular development workflows such as Git Flow, GitHub Flow, and trunk-based development, followed by hands-on introductions to GitHub Actions, CI/CD automation, repository security, and troubleshooting common Git errors. Rather than serving as a simple command reference, this book teaches you how to understand Git, choose the right command, predict its effect, and recover safely when something goes wrong.
