Getting started with software development means mastering version control. Git is the distributed system developers use to track code changes and collaborate effectively. Most projects live on repositories like GitHub, which Git lets you manage from your own machine. This guide covers installing Git on Ubuntu and the essential configuration steps to connect your local environment with your online presence.

First, prepare your system by opening the terminal with Ctrl + Alt + T. Update your package list using `sudo apt update`, then install Git with `sudo apt install git`. Once the process finishes, confirm the installation by checking the version number. This ensures you're running a current release and ready to proceed with setting up your identity.

Git needs to know who you are before you can commit any code. Link your local setup to your GitHub account by configuring your global username and email address. Use `git config --global user.name` and `git config --global user.email` to match your account details. Once confirmed with `git config --list`, you are ready to push and pull code. The next logical step is setting up SSH keys for secure, password-free authentication.
