Technical Documentation from Engineering
Transform engineering inputs like code, architecture diagrams, and design docs into clear technical documentation for different audiences.
Engineers write great code and terrible documentation. The architecture lives in someone's head, the API is documented in a 2-year-old README, and onboarding a new developer takes 3 weeks because nothing is written down. Turning engineering artifacts into clear docs for multiple audiences shouldn't require a technical writer.
Who it's for: engineering managers responsible for documentation standards, technical leads documenting system architecture for their teams, DevOps engineers creating runbooks and operational docs, platform teams writing developer-facing documentation, engineering organizations scaling without dedicated technical writers
Example
"Create technical documentation for our payments microservice" → Multi-audience doc set: architecture overview with system diagram description, API reference with endpoint documentation, developer onboarding guide with setup steps, operational runbook for on-call engineers, and a decision log documenting key architectural choices

## Your Role
You are an expert technical writer. Your job is to transform raw engineering artifacts into clear, audience-appropriate technical documentation that serves as a reliable single source of truth.
## Core Principles
- Start with "why" before "how"
- Use real examples from the actual system
- Document decisions (ADRs), not just current designs
- One diagram per concept, keep them simple
- Generate from code where possible to prevent staleness

What This Does
Converts raw engineering artifacts — code comments, architecture diagrams, design documents, and Slack conversations — into structured technical documentation suitable for different audiences (developers, ops, leadership).

Step 2: Gather Engineering Inputs
Collect code files, design documents, architecture diagrams, and any relevant team discussions.
Step 3: Start Using It

Say: "Create technical documentation for our payment processing service from these design docs and code files. Target audience: new engineers onboarding to the team."
Documentation Types
| Type | Audience |
|---|---|
| Architecture Overview | Engineers and architects — system design and decisions |
| Runbook | Operations — how to deploy, monitor, and troubleshoot |
| Onboarding Guide | New engineers — how the system works and how to contribute |
| API Reference | Integration developers — endpoints, schemas, examples |
| Decision Records | Future team — why decisions were made (ADRs) |
| System Diagram | All audiences — visual representation with context |
Tips
- Start with "why": Before explaining how the system works, explain why it exists
- Use real examples: Code snippets and API calls from the actual system
- Document decisions, not just designs: Architecture Decision Records (ADRs) prevent re-debating
- Keep diagrams simple: One diagram per concept — C4 model levels work well
Commands
"Create technical docs from these engineering files"
"Write an architecture overview for [service/system]"
"Generate a runbook for deploying and operating [service]"
"Build an onboarding guide for new engineers on [team]"
Troubleshooting
Docs too detailed for the audience Say: "Write for someone who's technical but unfamiliar with this specific system."
Information scattered across sources Ask: "Create a single source of truth that references but consolidates these inputs."
Docs go stale immediately Specify: "Generate docs from code where possible. Document stable concepts, not volatile details."
