Installing Git

Before you can use Git, you need to install it on your machine and configure your identity. This only needs to be done once per machine.

01.Install Git on Your System

On Windows: download the installer from git-scm.com and run it — accept all defaults. On macOS: open Terminal and run "xcode-select --install", or use Homebrew with "brew install git". On Linux (Ubuntu/Debian): run "sudo apt install git". Verify with "git --version".

02.Configure Your Identity

Every Git commit records who made it. You must set your name and email once after installing. This information is permanently embedded in every commit you create and is visible to all collaborators. Use --global to apply it to all repos on your machine.
