Welcome to GitLearn

Your interactive guide to mastering Git and version control.

What is Git?

Git is a free and open-source distributed version control system (VCS) designed to handle everything from small to very large projects with speed and efficiency.

It allows you to track changes to your files over time, so you can revert to specific versions, compare changes, and collaborate with others on the same project without overwriting each other's work.

Why Use Git?

Track History: See every change made to your project, by whom, and when.
Collaborate: Work with a team seamlessly. Git helps merge changes from multiple people.
Branching: Safely experiment with new features on "branches" without affecting the main project.
Revert Mistakes: Easily undo changes or go back to a previous, working state.
Industry Standard: Git is the most widely used VCS in software development.

Install Git

The easiest way to install Git on Windows is to use the official installer:

Download the latest Git for Windows installer from git-scm.com.
Run the installer and follow the on-screen prompts. The default settings are recommended for most users.
This will install Git Bash (a command-line tool), the Git GUI, and shell integration.
Verify installation by opening a new terminal (Git Bash or Command Prompt) and typing:

git --version

5.Alternative Method (using winget):

If you have the winget package manager installed, you can install Git with this command:

winget install --id Git.Git -e --source winget

Install winget tool if you don't already have it, then type this command in Command Prompt or PowerShell.

The easiest way to install Git on macOS is to install the Xcode Command Line Tools.

Open a new Terminal.
Try to run `git` by typing:

git --version

If you don't have Git installed, it will prompt you to install the command line tools. Follow the prompts.

Alternatively (using Homebrew):

If you have Homebrew installed, you can simply run:

brew install git

You can typically install Git using your distribution's package manager.

Debian/Ubuntu (apt):

sudo apt update
sudo apt install git

Fedora (dnf):

sudo dnf install git

Arch Linux (pacman):

sudo pacman -S git

After installation, verify it by running:

git --version

Active Branch: main

The Basic Workflow

1. Initialize a Repository

You start by creating a new Git repository in your project folder.

git init

2. Make Changes

You edit your project files (e.g., add new code, fix a bug).

3. Stage Changes

You select which changes you want to include in your next "snapshot" (commit).

git add <filename> or git add .

4. Commit Changes

You save your staged changes as a new snapshot in the project's history, along with a descriptive message.

git commit -m "Your message"

5. (Optional) Branch & Merge

Create a new branch to work on a feature, make commits, and then merge it back into the main branch when ready.

6. (Optional) Push to Remote

If collaborating, you "push" your commits to a shared remote repository (like GitHub).

git push origin main
