Spring RTS Engine

Hi.
Can someone write me in general how the whole lua thingy works?
I just want to understand the general structure of it..
I have no experiance in programming and im finding it difficult to understand hpw it is all built and how to look at it..

have you tried that post right above this wich says "lua beginners FAQ"?

You should learn to the lua language before tackling the spring lua interface.

P.S. I found those links better to learn from then the lua tutorial linked
at the top of the http://spring.clan-sy.com/wiki/Lua_Beginners_FAQ page.
