[Datastore] Log system?

(Kind of a request?) Umm anyways Im making a datastored nil logger. So when a player goes nil in a SB I can log them to remember them or kick them time they try to go nil. Basically what Im asking is..

Where would I start?

local NilTable={}

GetAsync()?
IncrementAsync()?
SetAsync()?
UpdateAsync()?

local CData=DS:GetOrderedDataStore('TestGravityNilLogs'):GetSortedAsync(false, 10)
local COutput=CData:GetCurrentPage()

for _,a in pairs(COutput) do
	table.insert(NilTable,{Player = '?'})
end

I can easily get the player from the nil stage, but how would I insert the data into a table next time I enter the server?
