1. Introduction

This tutorial is designed to give you a solid foundational understanding of Git, a powerful and popular version control system used by developers all around the world. By the end of this tutorial, you will be able to install Git, set up your first repository, and perform basic operations such as commit, push, and pull.

Prerequisites:
Basic understanding of command line interface and programming knowledge will be helpful but not mandatory.

2. Step-by-Step Guide

Installing Git

To install Git, navigate to the official Git website and download the version appropriate for your operating system. Follow the installation instructions provided.

Setting up a Git repository

After installing Git, the first step is to create a new repository. Navigate to the directory where you want to create the repository and run:

git init

This command initializes a new Git repository.

Making Changes

After you have made some changes in your project files, Git provides you with several commands to track these changes:

• git add . : This command adds all the files in the current directory to the staging area. Replace '.' with the specific file name to add a particular file.

• git commit -m "commit message" : This command saves your changes to the local repository. The commit message should be a brief description of the changes made.

• git status : This command shows the status of changes as untracked, modified, or staged.

Pushing Changes

To push your local changes to a remote repository (like GitHub), you would use:

• git remote add origin <URL> : This command links your local repository to the remote one. Replace '' with the URL of your remote repository.

• git push -u origin master : This command pushes your commits to the master branch of the remote repository.

3. Code Examples

Below are some practical examples of how to use the Git commands discussed.

# navigate to your project directory
cd /path/to/your/project

# initialize a new Git repository
git init

# make some changes to your project, then add them to the staging area
git add .

# commit your changes
git commit -m "Initial commit"

# check the status of your repository
git status

# link to your remote repository
git remote add origin https://github.com/username/repository.git

# push your changes to the master branch of your remote repository
git push -u origin master

You should see your changes reflected in your remote repository.

4. Summary

In this tutorial, we have covered the basics of getting started with Git, including installing Git, setting up a repository, making and tracking changes, and pushing to a remote repository.

As next steps, you could learn about branching and merging in Git, as well as how to resolve merge conflicts. You may find these resources helpful:

5. Practice Exercises

1. Exercise 1: Create a new repository, make changes to a file, and commit those changes.

2. Exercise 2: Connect your local repository to a remote repository on GitHub and push your commits.

Solutions:

1. Solution 1:

cd /path/to/your/project
git init
# make changes to your file
git add .
git commit -m "Made some changes"

1. Solution 2:

git remote add origin https://github.com/username/repository.git
git push -u origin master

Remember to replace 'username' and 'repository' with your GitHub username and repository name, respectively.

Keep practicing these commands until you feel confident with them, as they form the basis of most tasks in Git.
