Not sure if YouTube links are allowed here, but if you just search for automatic 1111 install tutorials, Sebastian Kamph’s channel is excellent and pretty much everything you’ll need to know is on there!
Keep an eye for his updated videos though, as you can imagine the tech moves so quickly that some of his more popular videos have been remade and updated!
I have a “world bible” that I created on onenote with all of my characters, locations, lore, etc. As part of that I have my stories plotted out in rough notes, then chapter by chapter in a table, (this often changes when actually writing but it’s a great foundation).
Lots of people use Obsidian or Notion to do the same thing. I already had onenote on all my devices, so it was easy just to add notes to my notes section if an idea came to me on the move that I could return to later.
I’ve tried to move to obsidian or notion a couple of times, but I think I have a certain efficiency now with my crude system, and it just seems to work for me.
