How-to Guides

A how-to guide addresses a real-world goal or problem, by providing practical directions to help the user who is in that situation.
A how-to guide always addresses an already-competent user, who is expected to be able to use the guide to help them get their work done. In contrast to a tutorial, a how-to guide is concerned with work rather than study.
A how-to guide might be: How to store cellulose nitrate film (in motion picture photography) or How to configure frame profiling (in software). Or even: Troubleshooting deployment problems.
