Well not really Wappler doesn’t uses Git yet - but with the installation of just for Windows some essential tools are included that you need to have for good SFTP - like SSH.
Microsoft recently also included those in the latest Windows 10 update, but those don’t work that well and are a bit broken
So by installing Git for Windows - you are just installing the right tools that Wappler can rely on.
If you were on a Mac or Linux you wouldn’t have this problem at all as those tools are there native included.
