To make it clear for people finding this guide after several updates from when it was posted, I will not be updating it unless something changes fundamentally, as I want most things to be figured out by play, rather than laid out explicitly.
Speaking which of, I am working on finishing up some content updates for the big 0.10.0 release, and then I will be working on a refactor to make future development easier and make room for better ideas in the future.
