Networking

I’ve made a simple game my brother and I like playing. I was telling him it was possible to make it multiplayer so we could play against each other.
The problem is I have no clue how this is done.
I’ve been searching and reading some of the documentation.
I’ve seen a lot of what needs to be done, but not how to do it.
Is there an Idiots Guide?
To keep it simple we both use the same WiFi.
Some questions:
How is the game set up / compiled. Are there 2 separate compiles (one for the server and one for the client)
or is it the same and the client just ignores the server stuff?
How do we connect?

Converting single-player to online is harder then going for it from the start.

You linked the “edit” function of the video (it sends me to my own videos) - this would be the correct link:

wow sorry hoax, well as bruno Xavier says, it is easier from start for múltiple reasons than convert something single Player.
