Documentation is not a side effect of building a system.
It is the first-class product surface.
When documentation is treated as a product, it has:
clear ownership,
defined users and goals,
quality standards,
and a lifecycle.
If documentation is neglected, the system becomes harder to adopt,
decisions slow down, and trust erodes.
Define documentation users and jobs-to-be-done
Documentation should be designed for the people who rely on it to make decisions.
Documentation audiences
Designer
Choose the right component for a design
Visual examples, usage guidelines, design tokens
Developer
Implement components correctly
API reference, code examples, props documentation
Product Manager
Make informed product decisions
Design principles, usage patterns, best practices
Support
Answer user questions accuratelyTroubleshooting guides, FAQ, common patterns
Identify primary audiences (designers, developers, product, support).
Assume documentation is "for everyone".Write task-oriented and decision-oriented content.Dump reference material without context or intent.
