How to Use Git and Github : A Complete Begginers Guide

In this tutorial, you will learn what is Git and GitHub and how to use them in the real-world web development projects.

so, let’s get started…

What is GIT?

GIT is a Distributed Version Control tool used for source code management. 

GIT was initially designed and developed by Linus Torvalds for Linux Kernel development.

What is Version Control System(VCS)?

Version Control System is a software that helps software developers to work together and maintain a complete history of theory work.

So GitHub is a tool that allows multiple developers to collaborate on the same project code so, all the developers have the entire copy of the latest code on their local system. if any developer made any changes to code then the latest code will also re-distributed to all developers.

• Git is used to tracking changes in the source code
• Git Allow multiple developers to work together
• Git Has the ability to handle the large project efficiently
• By using git you can know Who made what changes and when
• and last but not least you can Revert back at any time

CONCEPTS OF GIT

• Keep track of code history
• Takes “snapshots” of your files
• You decide when to take a snapshot by making “commit”
• You can visit any snapshot at any time
• You can stage files before committing

What is GitHub?

GitHub is a code hosting platform for version control and collaboration.

So GitHub is a Remote Server for source code management. It lets you and others work together on projects from anywhere and also provides a graphical interface to manage local repository code

Step 1: Download and install Git

Go to Git's official page or click here and download and install it on your machine.

Step 2: Create a Repository

Open Git Bash command Tool from your machine.

Create a “git-demo” folder

mkdir git-demo

Then Move to the “git-demo” folder

cd git-demo

Now Create a new Git instance for your project

git init

Now you will able to see a hidden folder named .git inside the “git-demo” folder

Create a file called demo.text in the git-demo folder and put some text into it.

Check the status of the repository to find out if there have been new changes by typing git status command in terminal

git status

It will show the newly added files list with red color with untracked files label.

Step 3: Commit changes to Git

Add the file you just created to the files you would like to commit the change.

git add demo.txt

Let’s commit those changes to the repository

git commit -m "New file added"

Step 4: Signup to GitHub and Creating a Repository

A repository is a storage space where your project lives. It can be local to a folder on your computer, or it can be a storage space on GitHub.

You can keep code files, text files, images or any kind of a file in a repository. You need a GitHub repository when you have done some changes and are ready to be uploaded. This GitHub repository acts as your remote repository.

Now go to the link: https://github.com. Fill out the signup form and click on “Sign up for Github”.

Then click on start new project

Enter any repository name and click on “Create Repository”. You can also give a description to your repository (optional).

Now you have created a new blank repository for your GitHub project

Step 5: Add your GitHub username to your Git Configuration

git config --global user.name <your github username>

git config --global user.email <your github email>

Step 6: Connect local and remote repository and push changes

Connect your local repository to your remote repository

git remote add origin <your repo url>

Push your files to the remote repository by typing the git push command

git push origin master

Congratulations, now you have done your first push on your remote repository, Take a look at your GitHub profile and you’ll see your new commits

Here’s what you accomplished in this tutorial:

• What are Git and GitHub
• Setup Git and GitHub on your machine
• GitHub Created an open-source repository
• Changed a file and committed those changes to GitHub
• Pushed local repository changes to the remote repository
