Effective Technical Writing for Developers

Writing Is a Superpower

The best developers I know are great communicators. They write clear documentation, persuasive RFCs, and blog posts that spread knowledge.

The Inverted Pyramid

Start with the conclusion, then provide supporting detail:

❌ "In 2004, Roy Fielding published his dissertation on REST..."
   (3 paragraphs of history before you learn anything useful)

✅ "Use PATCH for partial updates. Here's why and how:"
   (conclusion first, then explanation)

Show, Don't Describe

❌ "The function takes a string parameter and returns an array
    of words after splitting on whitespace."

✅ words("hello world")  // → ["hello", "world"]

Structure for Scanners

Most readers scan before reading. Help them:

1. Descriptive headings — "How to configure" > "Configuration"
2. Code blocks early — Don't bury the example
3. Bold key terms — Guide the eye to important concepts
4. Lists for steps — Numbered for sequences, bullets for options
5. TL;DR at the top — Respect busy readers

# Project Name

One sentence: what it does and who it's for.

## Quick Start

\`\`\`bash
npm install my-package
\`\`\`

\`\`\`typescript
import { thing } from 'my-package'
thing.doStuff() // → result
\`\`\`

## Why This Exists

The problem it solves (2-3 sentences).

Common Mistakes

• Writing for yourself, not your reader — They don't have your context
• Assuming knowledge — Define acronyms on first use
• Wall of text — Break into sections, add whitespace
• No examples — Abstract explanations without concrete code
• Outdated docs — Worse than no docs (misleading)

The Editing Process

1. Write the messy first draft (get ideas out)
2. Restructure for the reader's journey
3. Cut 30% of the words (be ruthless)
4. Add examples where you used abstract language
5. Read aloud — if you stumble, rewrite

One Weird Trick

Write the introduction last. You'll know what to introduce only after writing the body.

Good writing compounds. Every clear explanation you publish builds your reputation and helps someone struggling with the same problem.
