Multiplayer C++ tutorial that isn't based of of ThirdPersonTemplate

Hello,
Like the title says, I am looking for C++ tutorials that aren’t based of of third person template. I have gone through bunch of tutorials of multiplayer tutorials and i feel like I have a grasp on what’s happening but I would like to understand more about the engine and create a multiplayer project from scratch (“Basic Code Template”). I have searched a lot but I just can’t find anything
