TOOL: Come on, be a Git!

(no offense intended, and if you're offended, talk to Linus, who thinks he's a funny guy)
So, in order to interact with a Version Control System that someone called Git you have many options. Here are the 3 most common ones:

• Git command line client: https://git-scm.com/ - for command line lovers
• TortoiseGit: https://tortoisegit.org/ - for Project Managers and other "higher level" users

As a 3rd option: Sourcetree is a good client for developers with branching and merging needs (there are setups that require user Atlassian accounts, and others that will not require it): 
Go to the Atlassian web site for the most up to date versions (Atlassian is the company behind JIRA).
