Hey everyone 👋,
In this article I will introduce Git in general by explaining some basic terms 💡 so that in the next article 🌟 we will see the commands and some other things
✅ the first thing we need to know what’s Git ??
<h2>1. What is Git ❓</h2>
Git is a version management tool or VCS in English (version control system) which allows store a set of files 🗃️ while maintaining a timeline 🎞️ of all changes which were carried out on it.
It is part of the family of so-called decentralized VCS because in its operation each developer 👨‍💻 will have a complete local copy of the history of his source code.
✅ Now let’s explore some terms that one needs to learn to better understand the concept of Git .
<h2>2. Basic operation of Git ⚙️:</h2>
Git is a decentralized version management system. This means that the repository data Git is not located on a remote server but on your machine.
<h3>a Git repository :</h3>
A “repository” corresponds to the copy and import of all the files of a project
in Git.
There are two ways to create a Git repository:
<blockquote>
<ul>
<li>You can import 📥 an existing directory into Git.</li>
<li>You can clone 📋 an already existing Git repository.</li>
</ul>
</blockquote>
<h3>File states :</h3>
Git manages 3 states in which files can reside: modified, indexed, &amp; committed.
<blockquote>
<ul>
<li>Modified means that you have modified 🔄 the file but it has not been yet been validated in base.</li>
<li>Indexed (“staged”) means that you have marked a file modified in its version current so that it is part of the next project snapshot ➡️.</li>
<li>Committed means that the data is stored securely in your local database 🛢️.</li>
</ul>
</blockquote>
<h3>Work areas :</h3>
File states are linked to work areas in Git. Depending on its condition, a
file will be able to appear in this or that work area. Every Git project is composed of three sections: the working directory, the staging area and the repository.

<ul>
<li>The working directory corresponds to a unique extraction of a version of the project. Files are extracted from the compressed database located in the directory Git and are placed on disk so that they can be used or modified.</li>
<li>The staging area corresponds to a simple file, generally located in the Git directory, which stores information about what will be part of the next
snapshot or the next commit.</li>
<li>The Repository is where Git stores metadata and the database from the objects in your project. This is the main part or the heart of Git.</li>
</ul>
