now I understand that source tree sorta uses Git, so its is probably possible.
My team is using a local server I don’t think Git lets you do that.
I know this isn’t necessarily needed, but it would make things easier.
Side note: unfortunately for me I installed a internal version of git when I installed it. If any one knows how to change it to a separate version of git let me know (the installer seems to go to a modify mode and the option to add Git isn’t there)
First I recommend you to get basic understanding about version control programs 
So you don’t screw up your repo and lose all your work.
Yes you can use Source tree. It is a client for Git and Mercurial. You can also use command line for managing your repo.
I’m using Mercurial + TortoiseHg (a client) and it’s working great.
I think I figured it out its seems I already set up most of it I just needed to let unreal know about it I guess…
You can, as soon as you use supported protocols (ex. git or p4). Then, just set up in unreal and you are ready to go. You may have to do some command line tinkering in order to get these to push automatically etc. But don’t be afraid 
I use SourceTree, it works just fine
