Re: I really hate GIT
Change management will never be simple, GIT is initially hard work to get your head around, because it doesn't enforce a specific workflow upon you. It's upto you to come up with what works for your specific organization.
That said, there is GitFlow, which is a very good starting point for most people.
Documentation at Atlassian is as always superb: https://www.atlassian.com/git/tutorials/comparing-workflows/
