# CONCEPTUAL RULES _Conceptual rules_ help to clearly relay content by using an appropriate storyline. They comprise the first part of this guide with the rule sets [SAY](01-say.md) and [STRUCTURE](02-structure.md). The conceptual rules are based on the work of authors such as Barbara [Minto](https://www.amazon.com/Pyramid-Principle-Logic-Writing-Thinking/dp/0273710516). Their wide acceptance stems from their scientific, experimental, and practical experience basis.
