Should you add screenshots to documentation?
Whether software documentation should include screenshots divides authors between usability and maintenance concerns. Many argue images are invaluable for guiding beginners through complex or cluttered UIs, supporting visual learners, clarifying ambiguous text, and quickly revealing when instructions are outdated, especially in tutorials and UI-heavy workflows. Others stress that screenshots can be inaccessible, hard to localize and keep current, and should augment—rather than replace—clear, example-rich text and robust reference material, ideally supported by automation and testing to keep visuals in sync with the product.
When Screenshots Help
- Widely seen as valuable for GUI-heavy, complex, or cluttered UIs (IDEs, design tools, cloud consoles, Azure/AWS panels).
- Especially useful for beginners, infrequent users, or non-technical audiences who need concrete guidance and to know “where is the button / menu / icon.”
- Help users confirm they’re on the right screen and that their result “looks right.”
- Helpful in cross-language contexts when UI is localized but tutorials are not.
- Good for marketing/readme pages so users can see what a project looks like before installing.
Risks and Drawbacks
- Main concern is maintenance: UIs change often, screenshots go stale, and updating them is laborious.
- Accessibility issues if images lack alt text or text equivalents.
- Overuse (screenshot for every micro-step) clutters docs and can keep readers at “entry level” forever.
- Screenshots of terminal sessions and code are heavily criticized: no copy/paste, hard to update, large and inaccessible.
Target Audience, Learning Styles, and Doc Types
- Audience, context, and doc type matter more than any blanket rule.
- Visual learners and beginners benefit strongly; experienced users often prefer concise text and reference material.
- Clear distinction urged between: reference docs, tutorials/learning guides, how-tos, and explanations; screenshots are best for tutorials/how-tos, not as primary reference.
Outdated Docs & Versioning
- Some argue outdated screenshots erode trust.
- Others counter they’re useful because they visibly signal age and help users infer what’s changed, whereas wrong text alone misleads silently.
- Several suggest always including dates, versions, or captions on screenshots.
Automation and Tooling
- Multiple comments advocate auto-generating screenshots via test frameworks (Playwright, Cypress, CI pipelines) or using live HTML/iframes instead of static images.
- Idea: tight integration between tests and docs so UI or API changes break tests and force doc updates.
Text, Examples, and Alternatives
- Strong push for concrete examples (API, CLI, config) alongside or instead of screenshots.
- Many dislike video-only docs; videos and tours can complement but not replace searchable, skimmable text.
