Cant build engine from source

ok yall
I’m new to unreal engine and coding (literally started 2 days ago) and I am having trouble building UE4 in Microsoft visual studio. the updated source code on GitHub (updated last night) does not contain some of the files needed to build the engine such as UE4.sln. Help please. I have an amazing game idea that I want to bring to life and cant wait to get started

Hii JDsamps93,
Update all the packages by setup.bat file after that open UE4.sln file.
