How do I setup version control with Gaia Pro ?

[MoonBeam]

I use source tree for all my projects, but I am unsure on how to setup source with Gaia, quite often I want to make and revert changes. I don't know what folders to add in the repository

You would need to use the GaiaUserData. 
That holds the Sessions, Terrain Data, Terrain Layers, etc.

I have the same issue, EVen with a a .gitignore in the folder I am getting a huge amount of files that I need to put in git, which I am wary of. Is there a best practices for using gia with version control?

I typically use Plastic, I have not used git. 
Plastic is very easy to use and you can use multiple people on a project for free. 
I believe its 5 people and 5 gb / 15gb or something like that. 

You upload the project entirely, and then everyone can commit to it. 
As far as git is concerned, I am not sure.
