How the documentation is organized

This book uses four kinds of documentation:

• Tutorials are guided paths. They assume little context and aim for a working result.
• Topic guides explain how nacelle works and why it is shaped the way it is.
• How-to guides are recipes for specific tasks.
• Reference pages are precise descriptions of behavior, APIs, and protocol contracts.

Use tutorials when you are new, topic guides when you need a model of the system, how-to guides when you have a concrete job, and reference pages when you need exact details.
