Getting Started with Git and GitHub

Git is a powerful distributed version control system that allows you to track changes in your code and collaborate with others. GitHub is a popular platform for hosting and sharing Git repositories. This guide will help you get started with Git and GitHub.

Prerequisites

1. Install Git: If you haven't already, download and install Git for your operating system.

2. Create a GitHub Account: If you don't have a GitHub account, sign up for one.

Configuring Git

Before you start using Git, configure your identity:

$ git config --global user.name "Your Name"
$ git config --global user.email "[email protected]"

Replace "Your Name" and "[email protected]" with your name and email.

Creating a Git Repository

1. Initialize a New Repository: Open your terminal and navigate to the project folder. Use the following command to create a new Git repository:

$ git init

2. Add Files: Add the files you want to track to the repository using the following command:

$ git add .

3. Commit Changes: Commit your changes with a meaningful message:

$ git commit -m "Initial commit"

Working with GitHub

1. Create a Repository on GitHub:

   • Log in to your GitHub account.
   • Click the "+" icon in the top right corner and select "New Repository."
   • Follow the instructions to create a new repository.

2. Link Your Local Repository to GitHub:

   • Use the following commands to link your local repository to the remote GitHub repository:

$ git remote add origin <repository-url>
$ git branch -M main
$ git push -u origin main

Replace <repository-url> with the URL of your GitHub repository.

3. Push Changes to GitHub:
   • After making changes locally, commit them and push to GitHub:

$ git add .
$ git commit -m "Update something"
$ git push origin main

Cloning a Repository

1. Clone a Repository: To clone a repository from GitHub to your local machine, use the following command:

$ git clone <repository-url>

Replace <repository-url> with the URL of the GitHub repository you want to clone.

Branching and Pull Requests

1. Create a New Branch: To work on a new feature or fix, create a new branch:

$ git checkout -b new-feature

2. Make Changes and Commit: Make your changes, commit them, and push the branch to GitHub:

$ git add .
$ git commit -m "Implement new feature"
$ git push origin new-feature

3. Create a Pull Request: Go to your GitHub repository, switch to the new branch, and create a pull request to merge your changes into the main branch.
