Tutorials vs Guides vs Manuals
The following pages include tutorials, guides and manuals here are some definitions to help you distinguish between these three types of documentation:
- A Tutorial is a set of step-by-step instructions (exercises, try-this-try-that, etc). A tutorial can also be a sub-section of a guide.
- Guides are more conceptual description of how things work.
- Manuals are detailed descriptions of every command-line option for a utility or every function in a module etc.
