What is Git and Why Should Every Developer Use It?
If you're not using Git, you're likely naming folders like "final_v2_ok_definitive.zip". We see it all the time: developers losing hours reconstructing versions or overwriting working files. Git is not a luxury—it's the minimum to avoid wasting time and money.
At Meteora Web, we use Git on every project, from custom WordPress themes to complex Laravel platforms. It allows us to work in teams without stepping on toes and to revert mistakes instantly.
Git tracks every change. Each commit is a snapshot. You can branch to experiment without risk, merge work from multiple people, and revert when something breaks.
Action: Install Git from git-scm.com. Run git init in your project, then git add . && git commit -m "First commit". You've just started protecting your code.
How Does Branching Work and How to Handle Conflicts?
Branching is Git's superpower. A branch is a pointer to a commit. Create a branch (git branch feature-xyz), switch to it (git checkout feature-xyz), and work in isolation. When ready, merge back (git merge feature-xyz). Conflicts happen when two changes touch the same line. Git marks them with <<<<<<<. You edit, save, add, and commit the resolved file.

Keep branches short and merge frequently. Long-lived branches accumulate conflicts. Daily rebase or merge from main into your feature branch.
Action: Create a branch, modify the same file on both branches, simulate a conflict, and resolve it manually. Practice makes perfect.
Git Rebase vs Merge: When to Use Which?
Both merge changes, but differently. Merge creates a merge commit preserving history. Rebase rewrites history by applying your commits on top of the target branch. Use merge on public branches (main, release) for traceability. Use rebase on personal branches for a clean linear history. Never rebase shared branches.
Our workflow: git merge --no-ff for feature to main, git rebase main periodically on feature branches.
Action: Experiment on a test repo: create two branches, commit on both, try merge then reset and try rebase. Observe the log with git log --graph --oneline.
How to Use Git Stash for Temporary Work?
Need to switch branches mid-work without committing broken code? Use git stash. It saves your changes and cleans the working directory. Restore with git stash pop. Use git stash -u to include untracked files. Avoid long-term stashes; use a temporary branch instead.

Action: Modify a file, stash it, switch branches, come back, stash pop. See your changes restored.
How to Organize Workflow with Pull Requests and Code Review?
Pull requests are the standard way to propose changes. Create a branch, push, open a PR, request reviews, discuss, approve, merge. Enable branch protection rules to require reviews and passing tests before merging.
Even if you work alone, use PRs as practice.
Action: On GitHub, create a branch, push, open a PR to yourself, review and merge. Get used to the flow.
How to Automate Code Quality with Git Hooks?
Git hooks are scripts that run on events like pre-commit or pre-push. They can run linters, tests, or formatters. Example: a pre-commit hook that runs php -l on changed PHP files. Use tools like husky or pre-commit to share hooks across the team.
Action: Create a simple pre-commit hook in .git/hooks/pre-commit (remove the .sample suffix). Write a script that runs a linter. Make it executable (chmod +x). Try to commit code that fails the linter—it will be blocked.

How to Find a Bug with Git Bisect and Git Blame?
git bisect performs a binary search through commits to pinpoint the one that introduced a bug. git blame shows the last commit and author for each line of a file. Use bisect when you know a good and bad commit; use blame to understand why a line exists.
Action: In a repo with history, use git bisect to find a known buggy commit. Practice until you can isolate in 3-4 steps.
Gitflow vs Trunk-Based: Which Branching Strategy for Your Team?
Gitflow uses main, develop, feature, release, and hotfix branches. It's predictable and suitable for scheduled releases. Trunk-based development (TBD) uses short-lived branches merged to main multiple times a day, relying on feature flags. TBD requires CI/CD discipline. Start simple: main and feature branches. Add complexity only when needed.
Action: Assess your team size and release frequency. If you're 1-3 people, keep it simple. Gitflow is overkill for most small teams.

How to Set Up a CI/CD Pipeline with GitHub Actions?
GitHub Actions automates testing, building, and deploying. Add a YAML file in .github/workflows. Example: run PHPUnit on push to main and block merge if tests fail. Use secrets for credentials.
Action: Create .github/workflows/ci.yml with a simple test (e.g., echo). Push and see the action run in the Actions tab.
How to Manage a Monorepo with Git?
A monorepo holds multiple projects in one repository. Benefits: shared code, unified refactoring. Drawbacks: size, complex history. Use sparse checkout or tools like nx. Start with single repos unless you have clear cross-project dependencies.
Action: If considering a monorepo, first structure in subdirectories and learn git worktree.
Summary
Git is a mindset: every change tracked, every error recoverable, every collaboration orderly. Start today: install Git, commit regularly, add a hook, explore the log, enable PRs. Your code deserves professional version control.
