Most appliances comes with a user manual and a quick starter guide. The manual resembles most business presentations today, the quick starter guide is what you should aim to design.
Manual:
- Long
- Lots of words, long paragraphs, clumsy translations into multiple languages
- Regulatory disclaimers
- Logical structure
Quick starter guide:
- Short
- Visuals only (no need for languages)
- Only info that matters (regulatory statements are out)
- Story structure (the order of what needs to happen when you take the thing out of the box)
