What is Git and Version Control? (And Why You Need It)
- Git is the most widely used version control system in the world.
- Version Control is a system that tracks changes to files over time.
- Real-world analogy: Instead of saving multiple versions of a resume (resume_v1, resume_v2, resume_final), Git lets you keep one main file and tracks all changes automatically, preserving a full history.
For a more thorough walkthrough of the foundational concepts and first steps, you can refer to the Getting Started with Git: A Comprehensive Beginner's Guide.
Core Git Concepts for Beginners
The Three Main Areas of Git
- Working Directory: Your workspace where you make changes to files.
- Staging Area (Index): A draft space to prepare changes before saving them to history.
- Local Repository: The complete project history stored on your computer.
Key Collaboration Concepts
- Remote Repository: A version of your project hosted online for team collaboration.
- Branches: Parallel versions of your project to work on features independently.
- Pull Request: A request to review and merge changes from one branch to another.
- Merging: Integrating changes from one branch into another.
If you want to dive deeper into collaboration and advanced workflows, the Ultimate Git and GitHub Tutorial: Version Control & Collaborative Workflows will expand your skills significantly.
How to Install Git (Step-by-Step)
For Mac Users
- Go to the Git download page and select macOS.
- Install Homebrew first (package manager): copy and run the command in your terminal.
- Install Git:
brew install git - Verify: Run
gitin your terminal to see the list of commands.
For Windows Users
- Click the Windows icon on the download page.
- Select "Click here to download" for the latest version.
- Run the installer wizard:
- Accept terms → Choose default settings → Set default branch name to 'main' (modern convention).
- Click Finish, then open your terminal and run
gitto verify.
Configure Git
Set your identity (used to credit your work):
git config --global user.name "Your Name"
git config --global user.email "[email protected]"
Check your settings:
git config --list
Press
qto exit the configuration screen.
Essential Git Commands to Start Using
1. Initialize a Project
mkdir git-practice
cd git-practice
git init # Creates a new Git repository
2. Check Status (Your Most-Used Command)
git status # Shows tracked/untracked files and staging status
3. Stage Your Changes
git add . # Adds all changes to the staging area
4. Commit Your Changes (Save to History)
git commit -m "Initial commit"
Pro Tip: These three commands (
git status,git add,git commit) are the foundation of daily Git workflow.
Git vs. GitHub: What's the Difference?
| Git | GitHub | |-----|--------| | Version control system (tracks file changes) | Cloud platform for storing and collaborating on code | | Runs locally on your machine | Hosts remote repositories online | | Manages project history | Enables team collaboration with pull requests, issues, etc. |
In short: Git is the tool; GitHub is the platform that makes Git teamwork easy.
To understand how GitHub enhances Git-based workflows, exploring the Ultimate Git and GitHub Tutorial: Version Control & Collaborative Workflows is highly recommended.
Quick Start Workflow Summary
- Install Git on your machine.
- Configure your username and email.
- Create a folder and navigate into it.
git initto start tracking.- Make changes to files.
git add .to stage all changes.git commit -m "message"to save your progress.- Repeat steps 5-7 as you work.

Happy coding!
if you don't know the first thing about git or Version Control or the basic concepts you need to be successful with
Git then this video is for you today I'm going to teach you everything you need to know to get
started with Git if you're an absolute beginner this video will help you feel more confident installing configuring
and understanding git and Version Control you learn all the fundamental concepts you need to install configure
and get started started using git on your machine I'm kadaa and I'm so excited that you're here with me today
if you're new to the GitHub Channel be sure to hit the Subscribe button below so you don't miss any of your future
uploads let's get into it now what is git and why do you need to know it well git is the most widely used version
control system in the world Version Control is a system that tracks changes to files over a period of time so think
about your resume for a moment if you're like me you may have a few different versions of your resume over the course
of your career so you may have resumé rum V2 ré V3 and resume final saved on your laptop as four different files and
they may look something like this with Version Control you're able to keep just one main resume file because the Version
Control System AKA git tracks all the changes for you as long as you save them this means you're able to have a history
where you can view all the changes made to your resume and have copies of previous versions of your resume without
creating a new file every time okay so now that we know what git and Version Control are let's get into some basic
git Concepts that will be good to know the working directory is where you make changes to your files it is like your
workspace holding the current state of your project that git hasn't yet been told to track the staging area or index
is where you prepare your changes before committing them it's like a draft space allowing you to review and adjust the
changes before they become a part of the Project's history your local repository is your Project's history stored on your
computer it includes all the commits and branches acting as a personal record of the Project's changes a remote
repository is a version of your project hosted on the Internet or a network it allows multiple people to collaborate by
pushing to and pulling from the shared resource branches are parallel versions of your project they allow you to work
on different features or fixes independently without affecting the main project until you're ready to merge back
into them a pull requ is the way to propose changes from one branch to another it's a request to review discuss
and possibly merge the changes into the target Branch often used in team collaborations and finally merging is
the process of integrating changes from one branch into to another it combines the histories of both branches creating
a single unified history to use Git You need to download it on your machine so let's do that right now I'm using a
Macbook and while Mac OS comes with a pre-installed version of git we still want to download it so we have the most
up-to-date version let's go to the link on the screen then click Mac OS then we'll follow the onscreen instructions
first we'll install Homebrew Homebrew allows us to easily install software on our machines so let's copy this Command
right here pop open our terminals then paste the command and hit enter this will take
a while to run so let's give it a few moments once home bre is installed let's return to the download page and copy the
command to install git open up your terminal and paste the command Brew install git this will run
the installer so we can have git on our system when it runs successfully you now have get on your machine open up your
terminal and run the command get and you should see a list of all the commands available now if you're using a Windows
machine let's take a look at the downloads page click on the Windows icon and then select the link that says click
here to download and this will give us the most recent version of git for Windows once you have that folder on
your machine double click it and follow the onscreen wizard prompts click next to accept the terms click
next for the location to save G click next to keep the default settings let's reset the default Branch name to main
though as that's the new convention click next to accept the recommended path click next to accept
the bundled open SSH program don't worry about that right now and let's just click next for all the other options and
then click install once get is installed in the machine
click finish and open up your terminal run the command git and you should see a list of all the commands available
you're now ready to start configuring and using git now that we have git on our machines let's configure it open up
your terminal and type git config d-g Global user.name space then your username in quotes like
this git config dglobal user. mail space and then your email address tells get who made the change and gives you credit
for the work that was done if we run get config you can see all the other configuration options that are available
but we don't need to worry about those right now for now we can check our settings by running git config d-list
and this will return the configuration options we just set press the q key on your keyboard to exit this
screen okay now that we have a basic config let's go over some of the most basic terminal and get commands so you
can start start using the tool let's first get started by creating a new folder open up your terminal and type
mkdir get- practice to create a new folder then type CD get- practice to go into the folder that you just created
open the folder in a code editor okay great let's go back to the terminal and type touch hello. MD to create a new
markdown file in our folder navigate to your code editor and you'll see the file right there hello. MD okay let's go back
to the terminal and type get status this will return an error message because git is not initialized to initialize git is
to create a new git repository this is the first command you run in a new project so let's run get in it in this
folder which allows get to start tracking our changes then let's run get status again and you'll see that it's
currently tracking the m hello. MD file great this will show us our changes and whether they have been staged and it
will also show us which files are being tracked by git okay now let's run git ad period this will add all the changes
from the working directory to the staging area if we run git status we'll see a different color of the tracked
hello. MD file this indicates to us that it's currently in the staging area go back to your code editor and and
type the following hash I am learning to use glit exclamation point save the file and return to your terminal if I type
get status this will show me that there's been a change to the hello.my file let's run get add again then let's
create another file touch new file. Js and now let's run get status as you see one file is staged while the other file
is unstage as indicated by the different colors let's commit these changes by running
git commit DM initial Commit This command allows us to save our changes with a message attached to it one thing
to note is that you'll be using git status git ad and get commit very often while using git so it's important to
practice these commands you can see a list of all the available commands by running git in your terminal or you can
go to this website to see a list of the commands and know how to use them but before we wrap up quick question are git
and GitHub the same the answer to that is no git is a version control system that tracks file changes and GitHub is a
platform that allows developers to collaborate and store their code in the cloud git and GitHub work together to
make building scaling securing and storing software much easier thanks for watching I hope you found this helpful

Git is a version control system that runs on your local computer to track changes to your files and manage project history. GitHub, on the other hand, is a cloud-based platform that hosts remote repositories, enabling team collaboration through features like pull requests and issue tracking. In simple terms, Git is the tool for managing code versions, while GitHub is a service that makes it easier to share and collaborate on Git-managed projects.
For Mac users, the recommended method is to first install Homebrew (a package manager) by running the command from its website in your terminal, then type brew install git to install Git. For Windows users, download the latest version from the official Git download page, run the installer wizard (accepting default settings, but setting the default branch name to 'main'), and finish the installation. To verify success, open your terminal and run the git command to see the list of available Git commands.
Git operates with three core areas: the Working Directory is where you make changes to your files; the Staging Area (or Index) serves as a draft space to prepare and select which changes to include in your next snapshot; and the Local Repository stores the complete history of all committed snapshots on your computer. The typical workflow moves changes from the Working Directory to the Staging Area using git add, and then saves them as a permanent record in the Local Repository with git commit.
The foundational workflow begins with initializing a repository in your project folder using git init. Then, after making changes to your files, you check their status with git status, stage the changes using git add ., and finally save a snapshot of your progress with git commit -m "your message". This simple cycle of edit, stage, and commit forms the core of daily Git usage.
After installing Git, you must configure your identity, which will be attached to your commits. Use the commands git config --global user.name "Your Name" and git config --global user.email "[email protected]" in your terminal. You can verify your settings by running git config --list (press q to exit the list view).
A branch is a parallel version of your project that allows you to work on new features or fixes independently without affecting the main codebase. A pull request (PR) is a GitHub-specific feature that lets you propose changes from one branch to another, enabling team members to review, discuss, and approve the code before merging it. Together, branches and PRs enable safe, collaborative development by isolating changes and facilitating code review.
The git status command shows you the current state of your working directory and staging area, including which files are tracked, untracked, modified, or staged for the next commit. It is considered the most-used Git command because it provides a clear, real-time overview of what has changed and what needs to be done next, guiding you through every step of the workflow.
