This article will teach us how to set up Git and connect Git with GitHub.

In the programming world exist two popular version control systems:

• Git – distributed version control system.
• SVN – centralized version control system.

We will see how to install Git and use GitHub source code management services for your projects.

1. Install Git
   For Debian-based distributive/ubuntu, run the command:

sudo apt update && sudo apt install git

For Windows:

• Navigate to the  Git for Windows installer and download.
• Follow the instructions provided in the Git Setup wizard screen until the installation is complete.
• Open terminal and type

git --version

to be sure that you successfully installed Git.

For Mac:

Most versions of macOS have Git installed, if not:

• Navigate to the latest macOS Git Installer and download it.
• Follow the instructions and complete the installation.
• Open terminal and type:

git --version

to be sure that you successfully installed Git.

2. Sign up on GitHub

Visit the GitHub page, sign-up, and create empty repositories there.

As a result, you will see something like this:

3. Generate ssh keys:

ssh-keygen -t rsa -b 4096 -C "example@mail.com"

Press enter and create a passphrase to add an extra layer of security. Again, I recommend you do it. But if you don’t want you can skip it.

This command will create .ssh folder with id_rsa and id_rsa.pub files. To see it, just run the command below:

ls -a ~/.ssh/

4. Copy content from your id_rsa.pub file:

cat ~/.ssh/id_rsa.pub

5. Add ssh keys to the GitHub:

• Navigate to Settings

• Navigate to SSH and GPG keys
  

• Add ssh keys
  

That’s it. You have successfully configured Git and GitHub on your machine.
