In this video, we go over how to download the Unreal Engine source code from the Epic Games Github repository and build that source code in Visual Studio. In order to access the Github repo, we had to connect a Github account to an Epic Games account. We also discuss the various branches and tags in the repo so that you know which version of Unreal Engine you're using and how to retrieve the files for the version of Unreal that you are interested in. By the end of the video, you should be able to use your engine source build to develop games in the editor. The process covered in this video can be applied to other operating system platforms such as Mac and Linux, not just Windows.
