Summary  
This chapter explains how to use configuration commands to set global user identity parameters in a version control system, specifically by assigning your name and email with git config.  

General domain of usage  
Version control systems

You can interact with **Git** in two ways:

* Through a **graphical interface**, such as within an Integrated Development Environment (IDE);
* Through the **Terminal** (Git Bash).

In this course, you will use the **Terminal** (Git Bash) to work with **Git**, as it is often more convenient and faster. Learning to use the **Terminal** (Git Bash) will also help you navigate graphical interfaces more easily.


You should **follow along** on your computer throughout the course, run the commands, and experiment with them.


Note

Before running any commands, learn how to open the **Terminal** (Git Bash) on your operating system.


## Configuration

Proceed with the configuration. A **Version Control System** (VCS) should identify **who** made specific changes.

To set this up, configure basic information in **Git**, including your username and email address, by running the following commands:

To **run** a certain command means to enter/paste this command in the terminal window and press the **Enter** key.

Replace `email@example.com` with your actual **email address** and `username` with your preferred **username** (keep the **double quotes**). It is recommended to use the format `Firstname Lastname`, where `Firstname` is your **first name** and `Lastname` is your **last name**.

The main command used here is `git config`. When combined with the `--global` flag, it sets the value for all **Git repositories** you work with. Later in the course, you will learn how to set different values for specific repositories.


Choose all INCORRECT options to configure the email address in Git.

Git is the most popular version control system used by millions of developers around the globe. Whether you're a seasoned developer or a beginner, this course will equip you with the knowledge and skills needed to efficiently manage your software projects, collaborate with others, and master the art of version control.

First, we will provide an overview of version control systems in general. Afterwards we will discuss Git and learn the basics of creating a repository and making changes to it.

Now, it's time to discuss more advanced interaction with Git, which will boost your efficiency and make you more comfortable with some of the common Git workflows.

Being a Version Control System, Git allows you to undo changes when needed, so it's time to discover the techniques in Git to revert unstaged changes in the working tree, staged changes and even revert or overwrite commits.

Branches in Git are extremely useful when collaborating with other people, fixing bugs or developing certain features in your project. Without further ado, let's dive into all the nuances of working with branches.
