Git is a distributed version control system that allows developers to collaborate efficiently on software projects. Its main objective is to keep track of changes in the source code over time, facilitating collaboration and version management.

The purpose of Git is to track modifications and allow simultaneous collaboration among multiple users, integrating them coherently without data loss or work loss. It is widely used in software development but can also be employed in documentation projects, websites, and any other projects where version control is needed.

Why Use Git?

1. Complete and Detailed History: Git stores a complete history of all changes made, including who made each change and when.
2. Reduction of Errors and Conflicts: Facilitates the identification and resolution of conflicts.
3. Greater Security: Git's distributed architecture allows multiple copies of the repository, protecting against data loss.
4. Efficient Collaboration: Enhances coordination and collaboration among teams, even if they are geographically distributed.

Key Features of Git

• Distributed: Every developer has a complete copy of the project's history.
• Fast and Efficient: Local operations are extremely fast.
• Branching and Merging: Facilitates parallel work through branches that can be merged later.

Installing Git

To start using Git, you first need to install it. Here is how to install Git on different operating systems:

On macOS

You can install Git using Homebrew:

bash

On Ubuntu/Debian

bash

On Windows

It is recommended to download the installer from Git for Windows.

Getting Started with Git

Once installed, you can verify the installation and see the Git version by running:

bash

Initializing a Repository

To create a new repository, navigate to your project folder and run:

bash

This creates a new .git subdirectory where Git will store all version control files.

Making a Commit

Adding and committing changes to the repository is simple:

bash

Exploring the History

You can view the commit history using:

bash

This command displays a list of all commits in reverse chronological order, along with important details like the commit author, date, and associated message.

Git is a powerful and flexible tool that will provide you with robust control over your software development. Next, we will delve into the initial configuration and basic Git workflow.
