If you're here I assume you want to help make myCenter better. From here you can open pull-requests, or issues with the actual module.
First, download the MainModule, and drag it into Roblox Studio. Second, put it in ServerScriptStorage, at this point I'm assuming you already have your centers require that looks like this
require(123456787)("mcv5_loader_id:ffhdsyf8f87dsf87yds78yffs8fsd87fsd78");
We're going to want to change the numbers to
require(script.Parent.NameOfModule)("mcv5_loader_id:ffhdsyf8f87dsf87yds78yffs8fsd87fsd78");
From here you should be able to make changes to the module, and it show up in your game.
