So what I have found personally, is that asking questions gets the best results. So instead of feeding it too much generalized information, I ask LLMs to research what matters most for them in the current development space to create something that would be up to date, effective, clean, etc, etc.
My goal is to.. and I want to know more.
LLMs seem to do better when helping you learn than creating, as the predictions seem to change focus.
Then you could use the books to resource based on out final concept.
I find it to be SIGNIFICANTLY better than Projects in any other form, because the amount of layers you can create.
You can store the full books, have your workflows, etc.
