Are there plans to add Lua tutorials?

Question

So I've been tinkering with lua to learn to use an engine I want to use to build games with. I made demo coin toss game to test out the language. I wanted to throw it up here to see y'all's thoughts...
--[[ for some reason
lua can't randomise unless seeded
and then randomised 1 time
PRIOR to the variable you define]]
math.randomseed(os.time())
math.random()

repeat

--user inputs chosen face
io.write ("heads or tails: ")
guess = io.read()
if (guess == "heads")
then guess = 1
elseif (guess == "tails")
then guess = 2
else
io.write ("That is not a valid input ", "\n")
end
--[[careful with spelling
SciTE can't undo on the cmd what's already been typed
as it sends input to cmd as you type it]]

--setting coin variable
coin = math.random(2)

if (coin == 1) then
io.write ("heads", "\n")
else
io.write ("tails", "\n")
end
tonumber(guess)
until guess == coin
