Writing software documentation is like building furniture

Why software documentation needs more than words

In software documentation, images aren’t optional: they are essential. Screenshots help users confirm that they are in the right place. Icons guide them through actions without language barriers. Diagrams clarify workflows. And mock-ups? They future proof your content when interfaces change faster than you can update a support page.

But visuals must be purposeful: too many screenshots clutter, outdated ones mislead, and poorly edited photos confuse. A clean, simplified mock-up with callouts works better than a high-quality screenshot, because it removes noise and draws the eye to what really matters (and it's low maintenance).

The missed opportunity: conceptual visuals

Conceptual information and high-level flows explain how the software works, not just which buttons to click. It is crucial but often buried in paragraphs. Visualizing these flows will dramatically improve understanding, especially for onboarding, troubleshooting, or system design. If your documentation only shows the “how”, but not the “why” or “what”, users are left guessing.

The bigger picture

As our colleague, Pieterjan Vandenweghe, noted during DITA Europe, the “why” is becoming more and more important (read more here).

Think of a new team member learning a complex platform or process: a step‑by‑step task helps them perform it; a visual diagram helps them understand how everything hangs together. That clarity will pay off later, when something goes wrong, or a customer asks “What happens if we change this?”.

The real value of documentation is, of course, that it guides; but it empowers as well, it gives you tools. When you pair clear tasks with clear visuals you help users build confidence and awareness, so they can make informed decisions instead of blindly following "recipes".

So, what do software documentation and furniture assembly have in common?

Both leave you with a pile of parts and frustration, without the full picture. Following a software guide without conceptual visuals feels just as confusing. Luckily, we've got the missing piece now!

What’s your go-to visual when documenting software? And do you already explain the why behind the how in your docs?
