Git is a Version Control System that allows users to backup, collaborate, and maintain their projects. It is an industry standard tool that any confident software developer should have in their belt.
To install Git onto your computer go to https://git-scm.com and hit download.
Make sure you select the same OS (Operating System) that you are using along with either the 32 bit or 64 bit version which differs depending on your OS.
Now just follow the installer’s instructions and just go with the default settings presented. You will end up with five variations of Git. Git Bash is the one that you’ll be using for now.
