How do I Make an Online Multiplayer Game?

I'm trying to have a game option, so whenever you could play the game online or local hen it comes to players. I want to add online multiplayer, so my game could be access by anyone who has a desktop/pc (The game that will be supported on). If ya'll could tell me how to add it, can ya'll tell me how to use it please.
