Developing a User Guide for Web Applications
A User Guide is documentation for end users, not developers. The task: explain how to accomplish specific tasks in the interface without diving into technical details. A good User Guide reduces support burden and accelerates user adoption.
How User Guide Differs from Developer Docs
Developer Docs explain "how it works." User Guide explains "how to do it." Different audiences—different style and structure. User Guide:
- Is written from the perspective of user tasks, not system functions
- Uses screenshots and annotated images
- Avoids technical jargon or explains it at first mention
- Is organized by use cases, not interface sections

Tools
GitBook — convenient editor for non-technical authors, built-in search, custom domain. GitHub integration for synchronization. Popular for SaaS User Guides.
Notion — suitable for internal guides and small teams. But not for public documentation with custom branding.
Docusaurus / MkDocs — if documentation is stored in repository alongside code and full design control is needed.
Screenshots and Annotations
Screenshots become outdated with every UI update—this is the main User Guide problem. Solutions:
- Store screenshots in separate folder with versioning
- Use annotations (arrows, step numbers) via Figma or Snagit
- Record short GIFs for complex action sequences (Licecap, ScreenToGif)
- For frequent UI updates—describe actions in text, without screenshot dependency
Writing
Each article answers a specific user question. Article structure: one sentence about what it does → numbered steps → expected result → what to do if something goes wrong.
Search across documentation is mandatory. GitBook and Docusaurus have it out-of-the-box. Without search, a User Guide with 50+ articles is practically useless.
Timeline
Structuring and writing a User Guide for a typical web application (30–50 articles) takes 7–14 days. Setting up GitBook with custom domain and branding—1 day. Creating screenshots and annotations—2–3 days.
