Why are you looking in the wiki of CC when you're using OpenComputers? Also, there's documentation at https://ocdoc.cil.li/.

I don't think there is a tutorial for that, as OC doesn't do (official) tutorials, you're either supposed to look it up, or watch a tutorial. Also, if you're using CC when on the OC forum, go to the CC forum if there is one.

Also, that builder script isn't how you're supposed to do it. There's a robot API in the docs, to use it you just do

robot = require 'robot'

I haven't used that part of OC in a while though, so I might be off base. If I am, someone else correct me.

io.close() isn't how you close a file, it's file:close(), that's why it wasn't working, you didn't close the file properly.
