I am not understanding this with custom shutdowns, and badge names / descriptions?

Well, I am not really requesting I am just asking where I should start to learn this step where I should go on the wiki, etc.. So what I've seen games doing this, but I do not understand how they gather that data to change it into something new. I've been seeing like Custom shutdown names, custom badge names like Epik Face, and it has a custom description to it. Would it be like this?

local datab = game:GetService("BadgeService"):AwardBadge(game.Players.LocalPlayer.userId, 1234)

script.Parent.MouseButton1Down:connect(function()
    datab.Name = "Test"
    datab.Description = "asfasfasf"
end)
