Step-by-Step Procedure to Set Up Git and GitHub

1. Install Git SCM (Git)

  • Go to the official Git website.
  • Download the version suitable for your operating system (Windows, macOS, or Linux).
  • Follow the installation steps.

Verify Installation:

git --version

This should show you the Git version if it’s installed correctly.

2. Install Node.js (Optional, for JavaScript-based projects)

  • Go to the official Node.js website.
  • Download the latest LTS (Long Term Support) version.
  • Follow the installation steps.

Verify Installation:

node --version
npm --version

This should show the version of Node.js and npm (Node Package Manager).

3. Create a New Repository on GitHub

  1. Go to GitHub and create a new account (if you don’t have one).
  2. Once logged in, click on the + icon at the top right and choose New repository.
  3. Give your repository a name (e.g., my-first-repo), and choose whether it should be public or private.
  4. Click Create repository.

4. Open VSCode and Set Up Git

  1. Open VSCode (Download it from here if you don’t have it).
  2. Open the VSCode terminal by clicking on Terminal > New Terminal from the menu bar.

5. Create a Markdown File

In the terminal, create a README.md file:

touch README.md

Open this file in VSCode and add something like:

# My First Repository
This is a simple project to learn Git and GitHub.

6. Initialize Git in Your Project Folder

In the VSCode terminal, run:

git init

This will initialize Git in your project folder and create a .git folder to track all the version control changes.

7. Set Up Your Git User

Set up your Git username and email (the ones you use for GitHub):

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

8. Add and Commit Files to Git

Stage and commit your files:

  1. Stage the files (add them to Git):

    git add .

  2. Commit the files with a message and select main branch:

    git commit -m "Initial commit"
git branch -M main

9. Link Your Local Repository to GitHub (Remote) & push the code in main branch

  1. Go to your GitHub repository and copy the repository URL (e.g., https://github.com/username/my-first-repo.git).
  2. In the VSCode terminal, run: 
    git remote add origin https://github.com/username/my-first-repo.git
git push -u origin main

10. Login to GitHub via VSCode Terminal

To log in to GitHub through Git on your computer:

  1. Run:

    git config --global credential.helper cache

  2. The next time you push to GitHub, Git will ask for your GitHub username and password.

    For two-factor authentication (2FA):
    If you use 2FA on GitHub, you will need to use a Personal Access Token (PAT) instead of your password. Generate a PAT here.
