Chapter 1: The Importance of Version Control

In the realm of software development, version control is an indispensable skill for any developer.

The Challenge

Collaborating within a development team often leads to multiple individuals making changes to the same codebase simultaneously. Without a version control system, tracking these modifications becomes nearly impossible, complicating the integration of everyone's work significantly. Implementing a version control system simplifies this process, allowing developers to merge their contributions seamlessly.

Chapter 2: Understanding Git

Git is a free and open-source version control system designed for developers to monitor alterations in their code.

When you create a "repository" (or "repo") with Git, it acts as a directory where Git tracks all changes made to the contained files. Each time you modify your code, you "commit" these changes to the repository, effectively capturing a snapshot of your work along with a commit message that describes the updates.

This functionality allows you to revisit earlier versions of your code, compare changes between versions, and restore your code to prior states if necessary. Git facilitates concurrent collaboration, automatically merging changes from different contributors while minimizing conflicts, thereby enabling teams to tackle complex projects without interference.

Are you looking to install Git? Let’s dive into the installation process.

Installing Git on Windows

2. After downloading, run the installer by double-clicking the .exe file.
3. Follow the prompts to select your installation directory and components.
4. Choose your preferred terminal emulator during the setup; you can opt for the default option (Use Git Bash only).
5. Once installed, launch Git Bash by searching for it in the Start menu.

Installing Git on Mac

2. Open the downloaded .dmg file and double-click the installer package.
3. Agree to the license and choose your installation location, then select components.
4. After installation, access Terminal via Spotlight.

Installing Git on Linux

Most Linux distributions offer Git through their package managers. For instance, on Ubuntu, you can install Git by running:

sudo apt-get install git

After installation, verify that Git is operational by executing:

git --version

This command will display the installed Git version.

Using Git: Basic Commands

Once you've set up Git, familiarize yourself with these essential commands:

1. Initialize a new Git repository: git init
2. Create a new branch: git branch <new-branch-name>
3. Switch to a different branch: git checkout <branch-name>
4. Merge changes from one branch to another: git merge <branch-name>
5. Retrieve the latest version of the repository: git fetch

If you have a repository hosted on GitHub, you can clone it to your local machine using:

git clone <repo-url>

You can then execute Git commands directly from Git Bash or your code editor's terminal.

Integrating Git with VSCode

If you're using VSCode, installing Git allows you to run Git commands without manual entry. You can find the source control button located on the left sidebar:

To commit to a repository, enter a message in the text box and click the commit button. This action pushes your changes to the repository.

To switch branches, click the branch name at the bottom left of the screen, then select your desired branch from the search bar.

To create a new branch, click on the branch name again and select the 'create new branch' option.
