Getting started with Git and GitHub.

Source: Dev.to

Installation

Download the installer from the official site and run it as an administrator, following the prompts.

Git Configuration

git config --global user.name "name"
git config --global user.mail "name@gmail.com"
git config --global --list

The last command confirms that the profile was set up correctly.

Public and Private Key Generation and Setup

SSH keys provide password‑less authentication with GitHub.

Generate a new private SSH key (ED25519)

ssh-keygen -t ed25519 -C "your@email.com"

Retrieve the public key

The public key is stored at:

~/.ssh/id_ed25519.pub

Setting Up the Key on GitHub

1. Copy the contents of id_ed25519.pub.
2. In GitHub, navigate to Settings → SSH and GPG keys and paste the key.

Test the Connection

ssh -T git@github.com
