Install Git. It is a command-line (a text interface) tool that allows tracking the history of changes made to a file and, more importantly, working on different versions of that file simultaneously. It means you do not need to worry about overwriting someone else’s pending work when making changes.

Verify that the installation directory of Git is included in your system’s PATH variable.

Linux and macOSWindows

Follow the guide to update the PATH variable on Linux and macOS with the installation path of Git (by default /usr/bin/git).
