Complete Git and GitHub Tutorial for Beginners

Introduction

This tutorial is designed to guide beginners through the essentials of using Git and GitHub. By following this step-by-step guide, you will gain a solid understanding of version control, how to manage your code, and collaborate effectively with others using GitHub.

Step 1: Understand Version Control

• What is Version Control?
  Version control is a system that records changes to files over time so you can recall specific versions later. It is crucial for tracking changes in projects and collaborating with others.

• Benefits of Using Git

  • Keeps track of changes in your code.
  • Allows multiple developers to work on the same project.
  • Facilitates reverting to previous code versions if necessary.

Step 2: Install Git

• Download Git
  Visit Git's official website and download the installer suitable for your operating system.

• Installation Steps

  1. Run the installer.
  2. Follow the prompts, selecting your preferred options.
  3. Verify the installation by opening your command line or terminal and typing:

     git --version
     

Step 3: Configure Git

• Set Your Username and Email
  Open the command line and enter the following commands to configure your identity:

  git config --global user.name "Your Name"
  git config --global user.email "your.email@example.com"
  

Step 4: Create a New Repository

• Using Git Command Line

  1. Navigate to your project directory:

     cd path/to/your/project
     

  2. Initialize a new repository:

     git init
     

• Using GitHub

  1. Log into your GitHub account.
  2. Click on the "+" icon and select "New repository."
  3. Fill in the repository name and description.
  4. Choose "Public" or "Private" and click "Create repository."

Step 5: Add and Commit Changes

• Add Files to Your Repository
  Use the following command to stage your files:

  git add filename
  

  To add all files, use:

  git add .
  

• Commit Your Changes
  Commit your staged changes with a descriptive message:

  git commit -m "Your commit message"
  

Step 6: Connect to GitHub

• Link Your Local Repository to GitHub
  Add the GitHub repository as a remote:

  git remote add origin https://github.com/username/repository.git
  

Step 7: Push Your Changes

• Upload Your Local Changes to GitHub
  Use the following command to push your changes:

  git push -u origin master
  

Step 8: Collaborate with Others

• Cloning a Repository
  To work on someone else's project:

  git clone https://github.com/username/repository.git
  

• Creating a Branch
  To work on a new feature without affecting the main project:

  git checkout -b new-feature
  

• Merging Changes
  After making changes on your branch, switch back to the main branch and merge:

  git checkout master
  git merge new-feature
