Developers often struggle with poorly written documentation, leading to frustration and wasted time. Based on a survey of 100+ developers, here are the top complaints and actionable solutions to improve technical documentation.

1. No Real-World Examples

Developers need practical examples to understand how to implement APIs or libraries.

You Should Know:

  • Always include code snippets in multiple languages (Python, JavaScript, Bash).
  • Provide sample API responses with realistic data.
  • Use Postman collections or cURL commands for API testing.

Example:

curl -X GET "https://api.example.com/users" -H "Authorization: Bearer YOUR_TOKEN"

2. Outdated Endpoints

Obsolete API references break integrations.

You Should Know:

  • Use Swagger/OpenAPI for version control.
  • Automate docs with GitHub Actions to sync with code changes.
  • Deprecation warnings should include migration guides.

Example:

openapi: 3.0.0
info:
title: Sample API
version: 1.0.0
description: Updated endpoints as of 2024

3. Too Much Marketing, Not Enough Substance

Developers hate fluff—stick to technical details.

You Should Know:

  • Avoid buzzwords like “revolutionary” or “cutting-edge.”
  • Replace marketing jargon with benchmarks and performance metrics.
  • Use technical comparisons (e.g., “X is 20% faster than Y under Z conditions”).

4. No Versioning Context

Missing version info leads to compatibility issues.

You Should Know:

  • Tag docs with Git releases.
  • Include changelog links in every version.
  • Use semantic versioning (SemVer).

Example:

git tag -a v2.1.0 -m "Stable release with OAuth2 support"

5. Broken Auth Flow

Authentication errors block developers instantly.

You Should Know:

  • Provide step-by-step OAuth2 guides.
  • Include JWT token generation examples.
  • Test all auth methods before publishing.

Example:

import jwt
token = jwt.encode({"user_id": 123}, "SECRET_KEY", algorithm="HS256")

6. Unannotated Images

Screenshots without explanations are useless.

You Should Know:

  • Add numbered callouts to diagrams.
  • Use Markdown image alt text for clarity.
  • Provide interactive demos (e.g., JSFiddle).

What Undercode Say

Good documentation is developer UX. To improve:

  • Automate updates with CI/CD pipelines.
  • Validate commands before sharing.
  • Use Linux/CLI tools for efficiency:
    grep -r "deprecated" ./docs  Find outdated terms
pandoc README.md -o README.pdf  Convert formats
  • Windows users can leverage:
    Select-String -Path ".md" -Pattern "TODO"  Find unfinished sections

Expected Output:

  • Clear, executable examples.
  • Versioned and tested docs.
  • Zero marketing, 100% technical accuracy.

Improve your docs, and developers will trust your product. 🚀
