Applying Diátaxis Framework

Purpose

This Skill provides guidance for applying the Diátaxis documentation framework to organize and create documentation. Diátaxis categorizes documentation into four distinct types based on user needs and context.

When to use this Skill:

• Creating new documentation in docs/
• Organizing documentation structure
• Deciding which documentation type to write
• Reviewing documentation for proper categorization
• Understanding documentation organization principles

The Four Documentation Types

Tutorials (Learning-Oriented)

Purpose: Guide learners through a complete journey to achieve a specific learning outcome.

Characteristics:

• Learning-oriented (not task-oriented)
• Hands-on, practical examples
• Gradual progression from simple to complex
• Safety and encouragement for beginners
• Minimal assumptions about prior knowledge

Directory: docs/tutorials/

Example: "Data Tutorial - Beginner" teaching fundamentals step-by-step.

How-To Guides (Problem-Solving)

Purpose: Provide step-by-step instructions to solve specific problems or complete specific tasks.

Characteristics:

• Goal-oriented and task-focused
• Assumes basic knowledge
• Practical, actionable steps
• Specific to one problem/task
• Flexible order (can jump to relevant guide)

Directory: docs/how-to/

Example: "How to Add a New Nx App" - concrete steps for a specific task.

Reference (Technical Specifications)

Purpose: Provide factual, accurate technical information for lookup.

Characteristics:

• Information-oriented
• Accurate, comprehensive technical details
• Consistent structure
• Minimal narrative
• Lookup-friendly organization

Directory: docs/reference/

Example: "Monorepo Structure Reference" - technical specifications.

Explanation (Conceptual Understanding)

Purpose: Explain concepts, design decisions, principles, and context.

Characteristics:

• Understanding-oriented
• Conceptual, not procedural
• Provides context and rationale
• Explores alternatives and trade-offs
• Discusses WHY, not just HOW

Directory: docs/explanation/

Example: "Repository Governance Architecture" - explains six-layer system concept.

Quick Decision Matrix

User Wants To...	Documentation Type	Directory
Learn a skill	Tutorial	docs/tutorials/
Solve a specific problem	How-To	docs/how-to/
Look up technical details	Reference	docs/reference/
Understand concepts/WHY	Explanation	docs/explanation/

Organizing docs/explanation/

The explanation directory has special subdirectories:

• vision/ - Foundational purpose (WHY we exist, WHAT change we seek)
• principles/ - Foundational values and core principles
• conventions/ - Documentation standards and rules
• development/ - Software development practices
• workflows/ - Multi-step orchestrated processes

Common Mistakes

❌ Mistake 1: Mixing documentation types

Wrong: Tutorial that jumps to reference-style technical specs Right: Keep tutorials narrative and learning-focused; reference technical details in separate reference doc

❌ Mistake 2: Wrong directory placement

Wrong: Placing "How to configure X" in docs/explanation/ Right: Place in docs/how-to/ (it's task-oriented, not conceptual)

❌ Mistake 3: Reference as tutorial

Wrong: Making reference documentation tutorial-like with extensive narrative Right: Keep reference factual, structured, lookup-friendly

❌ Mistake 4: Explanation as how-to

Wrong: Step-by-step instructions in explanation documents Right: Explain concepts and rationale; link to how-to for implementation steps

Content Type Guidelines

Tutorials:

• Use encouraging, educational tone
• Include practical exercises
• Build incrementally
• Provide complete working examples
• Assume minimal prior knowledge

How-To Guides:

• Use imperative voice ("Do this")
• Focus on one problem/task
• Provide specific, actionable steps
• Assume basic knowledge
• Skip unnecessary explanation

Reference:

• Use consistent structure
• Provide comprehensive technical details
• Organize for easy lookup
• Minimize narrative
• Focus on accuracy

Explanation:

• Use conceptual, exploratory tone
• Explain WHY and context
• Discuss alternatives and trade-offs
• Provide background and rationale
• Connect to broader concepts
