how to install git pls help

For windows just download the installer from git-scm.com and follow it -- pretty straightforward.

macOS: brew install git (if using Homebrew) or just run git --version and let macOS prompt you to install the Command Line Tools.

Linux (Ubuntu/Debian): sudo apt update && sudo apt install git -y. Verify with git --version.

Windows: Install Git for Windows from https://git-scm.com/download/win. Choose the default options unless you have a specific reason not to. Use Git Bash for a Unix-like terminal experience.

Check your version after installing:

git --version
