Introduction to Git and Github

Have you ever asked yourself how developers used to keep track of changes they made to files before Git?
It must have been a tedious task, saving tons of files just to track changes. For instance, a developer might save files as file001, file002, file003, and so forth.

Thanks to Git and GitHub, with just a few commands a developer can save work and keep an eye on every change made to a file.

Git is a version control system that allows users to track changes in files.

On the other hand, GitHub is an online platform that helps developers store, share, and work together on code. Git works on your computer, while GitHub stores your Git projects on the internet.

why version control is important:

• Every change is recorded
• You can go back to older versions of your code
• You can see who made a change and when
• Multiple developers can work on the same project safely

How to Track Changes Using Git

To start tracking changes, you first need to create a Git repository.

Step 1: Initialize Git

Inside your project folder, run:

git init

This tells Git to start tracking the project.

Step 2: Check File Status

To see which files have changed:

git status

Step 3: Add Files to Staging

To prepare files for saving:

git add .

(The . means “add all changed files.”)

Step 4: Commit Changes

To save a snapshot of your work:

git commit -m "Describe what you changed"

A commit is like saving a checkpoint in a game—you can always return to it later.

How to Push Code to GitHub

Pushing means uploading your local code to GitHub.

Step 1: Create a Repository on GitHub

• Go to GitHub
• Create a new repository
• Copy the repository URL Step 2: Connect Your Project to GitHub

In your project folder, run:

git remote add origin

Step 3: Push Your Code
git push -u origin main

Now your code is stored on GitHub and accessible online.

How to Pull Code from GitHub

Pulling means downloading the latest code from GitHub to your computer.

To get updates from GitHub:

git pull origin main

This is useful when:

• You are working on multiple computers
• Other developers have made changes to the project

Summary

• Git tracks changes in your files
• Version control helps you manage and recover your code
• GitHub stores your projects online
• Push uploads your code to GitHub
• Pull downloads updates from GitHub
• Commits save your progress step by step
