My first ringworld!

[Ruatha]

In an not mentioned here PBW game that just reached turn 100 (Name starts with Net and is a lot of work) I just constructed my first ringworld, now I must colonize it.
I belive that there isn't much use in starting to construct Monolith facilities on it as I've done on my other planets.
So a space yard 3, Robotoid factory 3 (Already got systemic 3) and alot of mineral miner facility 3:s, is that the best I can make on it?
Or is there any good ideas on how to develop a ring world?
I have a starbase at it that can build weapon platforms.

(besides of this ringworld I'm really weak so don't start seeing me as the Mega-Evil empire and attacking me. We are a really nice species if you get to know us instead of kill us!!)
