Right now the stuff is mainly an FYI and working notes. It's made for mainly the audience of either Cinth or Blue, depending. In some cases information gets outdated and superseded by a later video, such as how we handle the LODs.
All of which is to say, when we start getting further in, I'll be making official videos that are more focused specifically for modders. Not for a few months on that yet, though; my hope is that most people during the alpha will be aiming themselves at helping us refine the core game itself (though of course people are free to do as they wish).
Certain things are likely a moving target until EA, as far as modding goes, and the risk of breaking changes is particularly high until then. Not that I don't want anyone to mod until EA, but I'm just letting you know where my own priorities and availability are between now and then, at least!
