so far there is only a shortcuts.txt (it's a developer tool so there is no gui and you need to use hotkeys and built in console to do things)
I managed to make a small tutorial on how to make a pool: https://imgur.com/a/xEsuI6N
and there are several scattered replies on this very itch.io forum (feel free to ask anything yourself)
I guess I really should compile all of these together into one big tutorial some day 🤔
