Quick answer
Git is a version control system that tracks changes to files over time, so teams can collaborate on the same codebase without overwriting each other’s work. Nearly every tech job — developer, data, DevOps, or cloud — expects basic Git fluency: cloning a repository, branching, committing, pushing, and opening a pull request. Most beginners reach comfortable everyday use in one to two weeks of regular practice.
If you are switching into tech, Git often shows up before your first technical interview question does — as a line on a job posting, a step in a take-home assignment, or the tool your onboarding buddy assumes you already know. The good news is that the everyday workflow is a small, learnable set of habits, not a deep specialty. This guide covers what Git actually does, the commands that matter, and how to build real fluency quickly.
What Git actually does
Git keeps a history of every change made to a project’s files, who made it, and why. Instead of emailing files back and forth or overwriting a shared document, each person works on their own copy, records changes as "commits," and Git merges everyone’s work together. That history also means mistakes are recoverable — you can always see, and usually undo, what changed and when.
- Repository — a project folder that Git is tracking the history of.
- Commit — a saved snapshot of changes, with a message describing what and why.
- Branch — an independent line of work, so you can build a feature without disturbing the main codebase.
- Remote — a hosted copy of the repository, usually on GitHub, GitLab, or Bitbucket.
- Pull request — a request to merge your branch into the main codebase, usually reviewed by teammates first.
The commands you actually need
Most working developers use a small, repeatable set of commands day to day. Learning these well matters far more than memorizing Git’s full command list.
| Command | What it does | When you use it |
|---|---|---|
| git clone | Downloads a copy of a remote repository | Starting work on an existing project |
| git status | Shows what has changed and what is staged | Before every commit, as a sanity check |
| git add | Stages changed files to be committed | After editing files, before committing |
| git commit | Saves a snapshot of staged changes with a message | After a logical, complete piece of work |
| git branch / checkout -b | Creates and switches to a new branch | Starting a new feature or fix |
| git push | Uploads local commits to the remote repository | Sharing your work with the team |
| git pull | Downloads and merges the latest remote changes | Before starting work each day |
The everyday workflow, step by step
- 1Pull the latest changes from the main branch before starting new work.
- 2Create a new branch for the feature or fix you are working on.
- 3Make changes, then stage and commit them in small, clearly described steps.
- 4Push the branch to the remote repository.
- 5Open a pull request so teammates can review before it merges into the main codebase.
- 6Resolve any feedback or merge conflicts, then merge once approved.
You do not need to master Git before your first tech job. You need to be comfortable with the ten commands you will use every single day.
Common beginner mistakes to avoid
A few habits separate confident Git users from people who dread it. Commit often, in small logical chunks, with messages that explain why a change was made, not just what changed. Always pull before you start work to avoid painful conflicts later. And never commit secrets, API keys, or credentials — once something is in Git history, removing it cleanly is far harder than not committing it in the first place.
How to build real fluency fast
Programs like MITS Edge's live online cohorts build Git into projects from week one, so you are not learning it in isolation — you are using it the way real teams do, with branches, pull requests, and code review baked into every hands-on project across cloud, data, and full-stack tracks. That project-based repetition is what turns Git from a memorized command list into a habit.
Build real project experience with Git and version control from day one.
Browse coursesFrequently asked questions
Do I need to know Git to get a tech job?+
Yes, for almost any developer, data, DevOps, or cloud role. Git is the standard way teams track and merge code changes, and interviewers routinely expect basic fluency, even for entry-level positions.
How long does it take to learn Git?+
The core workflow — clone, branch, commit, push, pull request — takes most beginners one to two weeks of regular practice to use comfortably. Deeper features like rebasing and resolving conflicts come with time on real projects.
What is the difference between Git and GitHub?+
Git is the version control software that tracks changes to files on your own machine. GitHub is a hosted platform that stores Git repositories online and adds collaboration features like pull requests, issues, and code review.
Can I learn Git without knowing how to code?+
Yes. Git tracks changes to any files, not just code, and the core commands are the same regardless of what you are building. Many data analysts and non-developers use Git purely for version control and collaboration.
What is the most important Git skill for a job interview?+
Comfort with the everyday workflow: cloning a repository, creating a branch, committing changes with clear messages, pushing to a remote, and opening a pull request. Most entry-level interviews do not go far beyond that.
