CLI experimental design
An experimental design for what the flatpak CLI could look like. There's a page that has a small amount of background research.
- Efficient information display
- Effectively structure information, including use of white space
- Avoid unnecessary visual noise
- Prioritise the most important information
- Don't show useless information
- Be succinct, but also try to speak like a human
- Follow standard English grammar and punctuation rules
- Be consistent:
- Consistent tone and terminology
- Consistent layouts
- Consistent information in output
- Play it straight - avoid gimmicks, use neutral language, stick to the point
- Anticipate errors and user intent. Be helpful.
