Documentation
dok-yoo-men-TAY-shun
Written resources that explain how to use a product, including guides, tutorials, API references, and troubleshooting information.
Documentation is the written backbone of any developer product. It includes quickstart guides, tutorials, API references, conceptual explanations, troubleshooting guides, and changelogs. For developers, documentation IS the product experience. They read docs before writing code.
Great documentation has three qualities. It is accurate (the code samples actually work), it is complete (common use cases are covered), and it is discoverable (developers can find what they need quickly). Most documentation fails on the third point: the information exists but developers cannot find it.
The best documentation sites (Stripe, Vercel, Supabase) invest as heavily in docs as in the product itself. They have dedicated technical writers, documentation engineers, and automated testing for code samples. Documentation is not an afterthought. It is a first-class product.
Examples
A company invests in documentation quality.
They hire a technical writer, implement automated testing for all code samples, add search analytics to find what developers are looking for, and survey users quarterly on documentation satisfaction. Satisfaction scores increase from 3.2 to 4.5 out of 5.
Documentation reduces support tickets.
The support team tracks the top 20 questions. The docs team creates content for each one. Within 3 months, support tickets drop 35%. The documentation pays for itself by reducing the support burden.
A docs site becomes the primary growth channel.
Google indexes 500 documentation pages. They rank for 2,000 long-tail keywords. Organic traffic to docs drives 40% of all signups. The documentation is not just support material; it is the most effective marketing channel.

Frequently asked questions
Who should own documentation?
A dedicated technical writer or documentation team, working closely with engineering and DevRel. Engineers should review docs for accuracy. DevRel should review for clarity. Product should ensure docs cover the most important use cases.
How often should documentation be updated?
Every time the product changes. Documentation should be part of the definition of done for every feature. Outdated docs are worse than no docs because they mislead developers and erode trust.
