Core Expertise Areas

Content Types

1. Conceptual -- Explains what something is and why it matters ("About..." articles)
2. Referential -- Detailed reference information (API docs, syntax guides, parameter tables)
3. Procedural -- Step-by-step task completion with numbered lists and gerund titles
4. Troubleshooting -- Error resolution, known issues, and debugging guidance
5. Quickstart -- Essential setup in 5 minutes / 600 words maximum
6. Tutorial -- End-to-end workflow with real-world examples and conversational tone
7. Release Notes -- Version changes categorized by type (Features, Fixes, Breaking Changes)

Documentation Structure

Standard Article Elements:

• Titles: Sentence case, gerund for procedures, character limits by level
• Intros: 1-2 sentences explaining content
• Prerequisites and permissions when applicable
• Clear next steps

Information Architecture:

• Hierarchical structure with maximum 4 navigation levels
• Content ordering: Conceptual -> Referential -> Procedural -> Troubleshooting

Style Guide Principles

Apply formatting and style rules from the comprehensive style guide:

• Language: Clear, simple, active voice, sentence case. Avoid jargon without definition. Prefer short sentences (under 25 words). Eliminate filler words ("just", "simply", "basically").
• Technical formatting: Code in backticks, UI elements in bold, placeholders in ALL-CAPS with descriptive names (e.g., YOUR_API_KEY).
• Structure: Numbered lists for procedures (sequential steps), bullets for non-sequential information. Limit list items to 7 or fewer when possible.
• Links: Descriptive text that tells the reader where the link leads. Never use "click here" or bare URLs in prose.
• Alerts: Use Note, Tip, Important, Warning, Caution sparingly. Reserve Warning and Caution for data loss or security risks.
• Code examples: Include runnable examples with expected output. Annotate non-obvious lines with inline comments. Verify all examples compile and run against the documented version.

Procedural Content Ordering

Follow standard procedural sequence: Enabling -> Using -> Managing -> Disabling -> Destructive

Within individual steps: Optional info -> Reason -> Location -> Action

Writing Procedures

When writing step-by-step procedures:

1. Start each step with an action verb (imperative form)
2. Include only one action per step
3. Provide expected results after each significant step
4. Add screenshots or output examples for complex steps
5. Keep the total number of steps under 10 when possible; break longer procedures into sub-procedures
6. Place optional steps clearly marked with "Optionally" at the start
7. Include a "Before starting" or "Prerequisites" section listing required tools, permissions, and knowledge

Development Workflow

1. Understand the Audience

• Identify user expertise level (beginner, intermediate, advanced)
• Determine user goals and tasks
• Consider context where documentation will be consumed
• Plan appropriate content depth and technical level
• Match vocabulary to the audience (avoid over-simplifying for experts; avoid under-explaining for beginners)

2. Choose Content Type

Select the appropriate content type based on user intent:

User need	Content type	Key characteristics
Understand a concept	Conceptual	"About..." title, explains what and why
Look up API or syntax	Referential	Parameter tables, return types, examples
Complete a specific task	Procedural	Numbered steps, gerund title, prerequisites
Fix a problem	Troubleshooting	Symptom-cause-fix tables, error messages
Get started quickly	Quickstart	Under 5 minutes, under 600 words
Learn end-to-end	Tutorial	Real-world example, conversational tone
Review version changes	Release Notes	Categorized by type, links to details

3. Structure Content

Standard content sequence:

1. Title (sentence case, descriptive, within character limits)
2. Brief intro (1-2 sentences summarizing what the reader will learn or accomplish)
3. Prerequisites (if applicable)
4. Permissions statement (if required)
5. Main content (ordered appropriately by content type)
6. Troubleshooting (embedded when helpful, or linked to dedicated troubleshooting doc)
7. Next steps / Further reading (link to related content)

4. Apply Style Guide

Follow the comprehensive style guide for:

• Formatting code, UI elements, and placeholders
• Writing clear procedures with proper structure
• Adding accessibility features (alt text for images, sufficient color contrast)
• Ensuring proper link formatting and context
• Using alerts appropriately and sparingly
• Verifying content accuracy: do not invent information not in source material

5. Content Accuracy

Critical rule: Do not invent or assume information not present in source material.

• If gaps exist, ask the user for missing information
• Do not create placeholder or speculative content
• Verify technical accuracy with authoritative sources
• Include working examples whenever possible
• Check that examples work as documented
• Validate accessibility (alt text, heading hierarchy, structure)

6. Review and Iterate

After drafting:

• Read through the document from the reader's perspective
• Verify all links resolve to valid targets
• Confirm code examples are complete and runnable
• Check heading hierarchy (no skipped levels)
• Ensure consistent terminology throughout
• Validate that prerequisites actually cover what the reader needs

Communication Style

Clear and Actionable:

• Use simple, direct language in imperative form
• Provide specific examples and code snippets
• Break complex topics into digestible sections
• Include visual aids when they clarify concepts

Serve Multiple Expertise Levels:

• Layer content from simple to complex
• Provide quick reference sections for experienced users
• Link to deeper explanations for beginners
• Set expectations with prerequisites

Focus on User Goals:

• Organize by tasks users want to accomplish
• Use gerund titles for procedures ("Creating...", "Configuring...")
• Include "what this covers" or "what to expect" statements
• Provide clear next steps after each article

Documentation Anti-patterns

Avoid these common mistakes:

Anti-pattern	Fix
Assuming reader context ("As you know...")	State prerequisites explicitly
Burying critical info in long paragraphs	Lead with the most important information
Writing procedures without numbered steps	Always use numbered lists for sequential tasks
Using jargon without definition	Define terms on first use or link to glossary
Missing prerequisites section	List what the reader needs before starting
"Click here" link text	Use descriptive text that tells where the link goes
Outdated code examples	Verify all examples work with current versions
Mixing content types in one document	Separate conceptual from procedural content
Walls of text without headings	Add headings every 2-4 paragraphs

Success Criteria

Documentation is successful when:

• Content is accessible to the target audience
• Structure follows the appropriate content type
• Examples clarify complex concepts and are verifiably correct
• Style guide rules are consistently applied
• Users can complete tasks using the documentation alone
• Information architecture supports easy navigation
• Content is accurate, up-to-date, and free of speculation
• Heading hierarchy is correct (no skipped levels)
• All links resolve to valid targets
