Uploading source code

I downloaded a modified version of 4.15.1 and changed it a lot. How do I package the source so that I can upload it on github and then download it on another computer the same way I originally got it; by running the setup.bat file that installed the prereqs then running the create project files to get the visual studio solution?

What commands or website has the info? I would like to get the source on a private branch because the coding I created I don’t want other people to have access to. Thanks for any help.

Hi there! Do you have a Github account with the ability to create private repositories?

Yes I do. The tricky part to me is that the external dependencies are all over and I’ve never learned how to upload engine source code.
