How to create working powershell module with optional flags

Question

I have a function that I am trying to make unto a module to use in my daily sripts. I want it to work kind of like (writeI -host "hello" -fore red -back black" where it has flags and values. I have already named is with psm1 and put it in the pwershell\modules\Make-Tbox folder.

How can I get this to work as I am caliing it from the MAIN example below? I would like the flags to be otional so it can function like regular cmdlets Thank you very much
