Prerequisite

Before we start, check which Git is installed on your system.

Run this command to verify your git installation:

Find system git version
git --version

My local git version is 2.43.2.

git version 2.43.2

Follow the official Git installation instructions if your Git installation is significantly older (or you don’t have git installed).

I used the Homebrew installation instructions for macOS.

Install git with Homebrew package manager
brew install git

With git installed and updated, we have all we need!

Assignment
