You'll notice this project is a bit of a placeholder at the moment, but the idea here is to provide some farming and ranching related content that doesn't quite fit into Thermal Expansion.
I'm not including all of this in Thermal Foundation because it will have a decidedly agrarian theme, and the point of Foundation is to just provide a base for the Thermal Series.
Strictly speaking, Thermal Expansion is not required, but that will mean that other mods are required to get the other metals (notably, Platinum for Enderium).
So at the moment, it's just Watering Cans. Underwhelming I know, but hey - there's no reason to sit on the content for another month or more while we get the rest ready, right?
