I would imagine a faq style would work best but if its about company data including mission, goals and financials including funding and donations, marketing team instructions, web design instructions and branding, and that type of stuff im not sure as the best way to format it

Are there some guidelines, examples or best practices for documents?

For the most part the AI is smart, but sometimes it acts dumb and wont provide information that i know is indeed in the document

For example i might ask who is Anne, and the chatbot wont have the information, but if i say do we have any vet experience it will provide that information and state it is Anne who has the experience, so Anne is indeed mentioned in the document
