Terra help on SpaceBuild2

im having troubles with understanding some of the things on spacebuild such as use of water and anything to do with terra. so i pretty much know the basics. could someone give me a link/ to something that could help me?

on some occasions water can be heated to steam and used on steam thrusters if installed / correctly.

terra crystals im not so sure about, or anything to do with terra
but the crystals are required to terra form , i heard somewhere that doing so and releasing the terra formed stuff into a planet can cause the planet to sustain life temporarly. im sot sure

not many links although there may be some help on face punch somewhere :slight_smile:
