When writing documentation, you need to establish a baseline of required knowledge and skills for your audience. You can choose any level, but deviating too far above or below that baseline will inevitably frustrate some readers.
When this happens, you can either make excuses or focus on solutions. Problems can be difficult, but with modern tools like AI systems, Google, or even books, it has never been easier to overcome them. If you don’t know what a Shoobababoo is or why you should use the quagmire instead of the hoobastank, you can look it up. Ideally, documentation would contain every answer with minimal need for external knowledge transfer, but the world doesn’t owe you that convenience.
