Getting Started with GitHub

If you’re new to GitHub or want to get started on the platform, here’s a step-by-step guide to help you kickstart your journey:

1. Create a GitHub Account

Before you can start using GitHub, you’ll need to create a GitHub account. Go to the GitHub homepage and sign up for a free account.

2. Install Git

GitHub is closely integrated with Git, so you’ll need to have Git installed on your local machine. Download and install Git from the official website.

3. Set Up Git

After installing Git, you’ll need to configure it with your GitHub account credentials. Open your terminal or command prompt and use the following commands, replacing <your-username> and <your-email> with your GitHub username and email:


Copy code

git config –global “Your Name”

git config –global “”

4. Create a Repository

To start using GitHub, you’ll need a repository. A repository can be seen as a project folder where you’ll store your code. To create a new repository, follow these steps:

Click on the “+” sign in the top right corner of your GitHub dashboard.

Select “New Repository.”

Fill in the repository name, description, and other settings.

Choose between making the repository public (visible to anyone) or private (restricted access).

Click the “Create repository” button.

5. Clone the Repository

Once you have created a repository, you’ll want to clone it to your local machine. Cloning a repository means creating a local copy of it that you can work on. To do this, follow these steps:

Click the “Code” button on your repository’s main page.

Copy the URL provided.

Open your terminal or command prompt and navigate to the directory where you want to clone the repository.

Use the following command, replacing <repository-url> with the URL you copied:


Copy code

git clone <repository-url>

6. Create a Branch

Branches are essential in Git for isolating changes and working on new features or bug fixes without affecting the main codebase. To create a new branch, use the following commands:


Copy code

git checkout -b new-feature

This command creates and switches to a new branch named “new-feature.” You can replace “new-feature” with the name of your feature or bug fix.
