Welcome to this useful guide that will help you to take your first steps in the unforgettable world of Git<\/a>! \n\nLet 's start from the beginning! Before getting deeper in the topic, we would need to establish the basic concepts that will act as a light in the middle of our dark path.<\/p>

<\/p>

<\/p>

Definition 1. <\/span> A version control system<\/em>, also known as source control , is a tool that will help us track and manage changes to software code.<\/p>

<\/p>

<\/p>

Definition 1.1.<\/span> A repository or \u2018repo\u2019 is a storage location for files, directories or any software package we would like to check and change.<\/p>

<\/p>

<\/p>

Definition1.2.<\/span> A change<\/em> is a modification of a file.<\/p>

<\/p>

<\/p>

Our starting point is a mental image that would probably be familiar to you:<\/p>

<\/p>

<\/p>

\"track<\/figure>

<\/p>

<\/p>

To make clear the previous definitions, let\u2019s see in detail two different types of working with them that will clarify the concept.<\/p>

<\/p>

<\/p>

Centralized version control. <\/span><\/h4>

<\/p>

<\/p>

The amazing \u2018Book of chess, dice and tables\u2019<\/em><\/a>\u00a0, commissioned by Alfonso X of Castile, is located in the Royal Library in the monastery of San Lorenzo de El Escorial. If one day you feel like you would like to read it, it has to be in person. Start checking your flights to Spain! However, maybe one morning you just wake up with an intense feeling of studying the manuscript deeply without moving from home. You would need a scanned version of the most important chapters. Obviously, carrying the manuscript home or copying it all are not considerable options. If in a specific moment, the best chess player in the world or even Alfonso X decided to add new moves, then, it will be needed a permit or going to the library. The way of modifying new chess moves represents how centralized control versions from the XIII century works.<\/p>

<\/p>

<\/p>

Distributed version control. <\/span><\/h4>

<\/p>

<\/p>

Congratulations! You are a lucky person! Your favorite professor uploads all class notes in a well-organized platform. We all have access to Geometry lecture notes. You work on them, doodle, add graphs. You don't need to be in class to see the notes on the board, because you can have them downloaded (offline). Your teacher can't see the mathematical atrocities you write either because you haven't sent her your modifications yet (push\/pull files). The typos have to be sent to the professor who will change the file, and students will not encounter an unnecessary minus sign again. Your wonderful professor is acting as a central repository, and in the described processes our protagonist is described : Git. A distributed version control system.<\/p>

<\/p>

<\/p>

Now that we've got a handle on what Git is, you may be asking yourself a few different questions. Let 's start answering them.<\/strong><\/span><\/p>

<\/p>

<\/p>

1. Do I need to know any other terms before I start?<\/span><\/p>

<\/p>

<\/p>

In addition to keeping in mind the definitions we have established as the foundation of our path, we should add a few more concepts to our vocabulary.<\/p>

<\/p>

<\/p>

Definition 2. <\/strong>A historical record is the traceability of the file. It allows us to answer the questions: Who modified it? When? Why?<\/p>

<\/p>

<\/p>

Definition 3. <\/span>\u00a0 A commit is the minimum unit of storage.<\/p>

<\/p>

<\/p>

2. What are we using Git for?<\/span><\/p>

<\/p>

<\/p>

Tomando el s\u00edmil de la forma de trabajar de tu profesora favorita, podemos sacar algunas conclusiones sobre qui\u00e9n puede ser part\u00edcipe en el control de versiones.<\/p>

<\/p>

<\/p>

Taking the analogy of your favorite professors\u2019 way of working, we can draw some conclusions about who can be involved in version control.\n\nYou can use it privately to manage the changes you make to your work. We can also use Git to collaborate with other people. For example, it allows us to synchronize all the collaborators on a project through a central repository. In this case the central\/remote repository is called GitHub<\/span><\/a>.<\/p>

<\/p>

<\/p>

3. How do we work with file modifications?<\/span><\/p>

<\/p>

<\/p>

To answer this question, we need to consider three identities in which we will be passing the files:<\/p>
