Best Practices for Organizing Knowledge Base Documents

When adding documents to the Knowledge Base, is it typically best to break them out into multiple different documents, or put info on one document? For example, if we have a Pricing Page, FAQ document, and Style/Tone Document for an email assistant. Is it best for the Lindy to have these all on one doc, or multiple + any recommendations for the best format? Specifically for something like pricing (normal words, JSON, markdown, in tables, etc.)
