Technical Documentation Prompt Template

Write clear technical documentation with overview, installation, API reference, examples, and troubleshooting for developers.

The Prompt

ROLE: You are a developer relations engineer and technical writer who has written documentation for open-source libraries with millions of downloads — you know that great docs are the difference between adoption and abandonment. CONTEXT: You are writing documentation for a library, API, or tool. The readers are developers — they are impatient, they will skip straight to the example they need, and they will abandon the docs the moment they get confused or bored. The documentation must work for three different reading modes: sequential (first-time learner), lookup (experienced user finding a specific method), and troubleshooting (frustrated user something has broken). TASK: Write complete technical documentation for the library, API, or tool described below. RULES: • The overview must tell a developer in 30 seconds: what problem it solves, what the simplest integration looks like, and who it's for • Every function/method in the API reference must have: purpose, parameter types and descriptions, return type, a working code example, and any exceptions it throws • Code examples must be complete and runnable — no "..." placeholders mid-example • The troubleshooting section must address real failure modes, not obvious ones (don't document "check your spelling") • Installation section must cover the primary package manager and note any peer dependencies CONSTRAINTS: Use [LANGUAGE] for all code examples. If the library has TypeScript types, include them. Navigation-first structure — assume developers will search or jump directly to what they need. EDITABLE VARIABLES: • [LIBRARY_API_TOOL] — what you're documenting • [LANGUAGE] — primary programming language • [AUDIENCE_LEVEL] — beginner, intermediate, or senior developer • [KEY_USE_CASES] — the 3 most common things developers use this for OUTPUT FORMAT: # [Name] ## Overview (what it does, simplest example, who it's for) ## Installation ## Quick Start (working example in under 10 lines) ## Configuration ## API Reference (each function: description, params, return, example, throws) ## Examples (3 complete real-world use case examples) ## Troubleshooting (common errors with causes and fixes) ## Contributing (if open source) ## Licence QUALITY BAR: A developer who has never used this library should be able to complete their first integration using only these docs, without googling anything or opening a GitHub issue.

Why this prompt works

The three reading modes (sequential, lookup, troubleshooting) provide a concrete design target that prevents documentation from becoming either a tutorial-only or reference-only document. 'Complete and runnable' code examples is the most important single rule — the most common documentation complaint is non-working examples.

Tips for best results

  • Paste in your actual source code or type definitions — the AI will generate far more accurate API reference docs than if you describe the API in prose
  • Generate the Quick Start section first and test it independently — if it doesn't run, the rest of the docs are built on a broken foundation
  • The troubleshooting section benefits enormously from your real GitHub issues and Stack Overflow questions — paste in the top 5 and ask the AI to write solutions
  • Ask the AI to generate the docs in Markdown, then in JSDoc format, then in OpenAPI YAML — choose the right format for where the docs will live
