Writing Best Practices

Who This Is For: Technical writers, content strategists, developers documenting code, and anyone responsible for creating clear, professional technical content.

When to Use This Guide: You're establishing documentation standards, training new writers, improving existing content quality, or building a style guide for your organization.

What You'll Learn: Industry-proven writing techniques, style guidelines, formatting standards, information architecture principles, and strategies to make complex technical concepts accessible to diverse audiences.

Why Writing Best Practices Matter

Great technical writing isn't about using fancy words—it's about getting users from confusion to clarity as quickly as possible. Well-written documentation reduces support tickets, improves user satisfaction, accelerates feature adoption, and saves your organization money.

Real-World Impact: A software company rewrote their installation guide using the principles in this guide. Result? Support tickets related to installation dropped by 60%, new user onboarding time decreased by 45%, and customer satisfaction scores increased by 35%. The difference? Clear structure, concise language, and practical examples.

Core Principles

1. Know Your Audience

Understanding your readers is fundamental to effective technical writing:

Identify User Personas: Define who will use your documentation (developers, end-users, administrators)
Assess Technical Level: Match complexity to audience expertise
Consider Context: Where and how will they access your docs?
Language Preferences: Account for international audiences and localization needs

2. Clarity and Conciseness

Write content that's easy to understand and quick to consume:

Do's:

Use active voice: "Click the button" (not "The button should be clicked")
Keep sentences under 25 words when possible
Use simple words: "use" instead of "utilize"
Break complex ideas into smaller chunks

Don'ts:

Avoid unnecessary jargon and buzzwords
Don't use passive constructions excessively
Eliminate redundant phrases ("in order to" → "to")
Skip filler words ("actually", "basically", "really")

3. Consistent Terminology

Maintain consistency throughout your documentation:

Create and follow a terminology glossary
Use the same term for the same concept (e.g., don't alternate between "user" and "customer")
Define acronyms on first use
Follow industry-standard naming conventions

Document Structure

Effective Organization

Title (H1)
├── Introduction/Overview
├── Prerequisites
├── Main Content (H2)
│   ├── Subtopics (H3)
│   ├── Code Examples
│   └── Visual Aids
├── Troubleshooting
└── Related Resources

Best Practices for Headings

Use descriptive headings: "Configure Database Connection" (not "Configuration")
Maintain hierarchy: Don't skip levels (H1 → H2 → H3)
Keep consistent style: Choose between sentence case or title case
Make them scannable: Users should understand content by reading headings alone

Include TOC for documents longer than 3 screens:

Auto-generate when possible
Link to major sections
Update when structure changes
Consider sticky/floating TOC for long pages

Writing Style Guide

Voice and Tone

Active Voice Example:

 "The system processes the request"
 "The request is processed by the system"

Appropriate Tone:

Instructional: Confident and direct
Explanatory: Clear and educational
Error Messages: Helpful and actionable
Release Notes: Professional and informative

Grammar and Punctuation

Serial Comma (Oxford Comma):

 "Install Node.js, Python, and Docker"
 "Install Node.js, Python and Docker"

Contractions:

Generally avoid in formal docs ("do not" vs "don't")
OK for conversational tutorials and blog posts
Maintain consistency within each document type

Second Person:

 "You can configure the settings in the dashboard"
 "Users can configure the settings" or "One can configure"

Formatting Conventions

Code and Commands

Inline code: Use backticks for file names, commands, variables

Run `npm install` to install dependencies.
Edit the `config.json` file.
Set the `API_KEY` environment variable.

Code blocks: Include language identifier for syntax highlighting

```bash
npm run build
npm start
```

```javascript
const config = {
  apiUrl: 'https://api.example.com',
  timeout: 5000
};
```

Lists

Numbered Lists (Sequential Steps):

Open the terminal
Navigate to project directory
Run the install command
Verify installation

Bulleted Lists (Non-Sequential Items):

- Feature A: Description
- Feature B: Description  
- Feature C: Description

Tables

Use tables for comparative or structured data:

Feature	Description	Required
API Key	Authentication token	Yes
Timeout	Request timeout in ms	No
Base URL	API endpoint	Yes

Content Types

Tutorials

Structure:

Introduction: What will users learn?
Prerequisites: What do they need before starting?
Step-by-step instructions: Clear, numbered steps
Verification: How to confirm success?
Next steps: Where to go from here?

Visual Elements

When to Use Images

Include screenshots for:

User interface navigation
Complex configurations
Visual verification steps
Error messages

Best practices:

Use annotations (arrows, highlights)
Keep file sizes optimized (less than 500KB)
Use consistent image sizes
Provide alt text for accessibility

Diagrams and Charts

Architecture diagrams:

┌──────────┐      ┌──────────┐      ┌──────────┐
│  Client  │─────▶│   API    │─────▶│ Database │
└──────────┘      └──────────┘      └──────────┘

Tools for diagrams:

Mermaid.js (text-based diagrams)
Draw.io / Lucidchart
PlantUML for sequence diagrams
Excalidraw for hand-drawn style

Code Examples

Effective code examples:

Complete and runnable
Include relevant context
Show realistic use cases
Add inline comments for clarity
Follow language conventions

//  Good Example: Clear, complete, commented
async function fetchUserData(userId) {
  try {
    // Make API request with authentication
    const response = await fetch(`/api/users/${userId}`, {
      headers: { 'Authorization': `Bearer ${token}` }
    });
    
    // Parse and return JSON data
    return await response.json();
  } catch (error) {
    console.error('Failed to fetch user:', error);
    throw error;
  }
}

Accessibility

Writing for Screen Readers

Meaningful link text: "View installation guide" (not "click here")
Image alt text: Describe the content and purpose
Heading hierarchy: Maintain logical order (H1 → H2 → H3)
Table headers: Use proper <th> elements

Internationalization

Considerations for global audiences:

Avoid idioms and cultural references
Use clear date formats (YYYY-MM-DD or spell out: "January 8, 2026")
Provide currency contexts ($100 USD)
Consider right-to-left (RTL) languages
Support translation workflows

Version Control

Documentation as Code

Treat documentation with the same rigor as code:

# Feature branch for doc updates
git checkout -b docs/update-api-guide

# Make changes and commit
git add docs/api-reference.md
git commit -m "docs: update API authentication section"

# Create pull request for review
git push origin docs/update-api-guide
