Complete Guide to Mastering Git Workflow
Master Git version control from basics to advanced workflows. Learn branching strategies, merge vs rebase, and essential commands for development teams.
Understand Git Fundamentals
Git tracks changes to files through snapshots called commits. Every commit has a unique hash and points to its parent. The three areas of Git are: working directory (your files), staging area (changes ready to commit), and repository (committed history). Understanding this model is key to everything else. Use git status constantly to see which area your changes are in.
Master Essential Commands
The daily workflow commands you need: git add (stage changes), git commit (save snapshot), git push (upload to remote), git pull (download and merge), git branch (create branches), git checkout or switch (change branches), git merge (combine branches), and git log (view history). Use our git command generator to quickly find the right command for any scenario including undoing mistakes and resolving conflicts.
Adopt a Branching Strategy
For most teams, trunk-based development with short-lived feature branches works best. Create a branch for each feature or bugfix, keep branches small (merge within 1 to 3 days), and delete branches after merging. Larger teams may use GitFlow with develop, release, and hotfix branches. The key principle: main branch should always be deployable. Never commit directly to main.
Handle Merges and Conflicts
Merge conflicts occur when two branches modify the same lines. Git marks conflicts with angle bracket markers in the file. To resolve: open the file, choose which version to keep (or combine both), remove the conflict markers, stage the file, and commit. Reduce conflicts by keeping branches short-lived, pulling main frequently into your branch, and communicating with teammates about shared files.
Pro Tips
- Write descriptive commit messages: 'fix: resolve null pointer in user login' not 'fix bug'
- Use git stash to temporarily save work-in-progress when switching branches
- Set up git aliases for frequently used commands (git config --global alias.co checkout)
- Never force push to shared branches — it rewrites history and affects all collaborators

Frequently Asked Questions
What is the difference between merge and rebase?
Merge creates a new commit that combines two branches, preserving the full history of both. Rebase rewrites your branch history to appear as if it branched from the latest point of the target. Use merge for shared branches (preserves context), rebase for personal feature branches (creates cleaner linear history). Never rebase branches others are working on.
How do I undo a commit?
Use git revert HEAD to create a new commit that undoes the last one (safe for shared branches). Use git reset --soft HEAD~1 to undo the commit but keep changes staged. Use git reset --hard HEAD~1 to completely discard the last commit (dangerous — loses changes). For pushed commits on shared branches, always use revert, never reset.
What is a good commit message format?
Follow the Conventional Commits standard: type(scope): description. Types include feat (new feature), fix (bug fix), docs (documentation), refactor, test, and chore. Keep the subject line under 72 characters. Add a body for complex changes. Examples: 'feat(auth): add Google OAuth login' or 'fix(api): handle null response from payment service'.
