I've always been a fan of trying to organize my writing with several levels of complexity embedded. For example, when writing any sort of FAQ or explanation, I would briefly outline the steps, and then proceed to explain each one in further detail so that a lay audience may understand.

Either way, you're making assumptions about the level of minimum expertise of your audience.
