Single/Multiplayer, Touch & Vive blueprint only Template

I’m confused. That’s the first time I downloaded the project, but pdf says to follow some paths that don’t exist anymore.

https://github.com/EpicGames/UnrealEngine/tree/4.22

Can I use the default UE4 4.22 version from Epic Launcher? Github link doesn’t exist.

“Make the modifications needed to the engine, as specified in pdf document”

Which pdf would be this?

Please help =(
