Grimoire HELP

Is there any instructions on how to use this? I cannot find anything

No there aren't any instructions on using this. Few people were working on writing in details about using it, don't know if they are done yet.

I was the only one who mentioned it jsyk. I am at a crossroads so if anyone wants to take over it'd be great.
(Writing an entire complex is the same as an essay at this point to avoid FAQs and user-related errors)
