Explanation
Understanding-oriented documentation - Concepts, design decisions, and the "why" behind ngit-grasp.
What Is Explanation?
Explanation documentation helps you understand concepts and design decisions, providing context and discussing alternatives.
Characteristics:
- ✅ Understanding-oriented (clarify concepts)
- ✅ Theoretical (ideas and design)
- ✅ Discuss alternatives
- ✅ Provide context and background
- ✅ Answer "why" questions
Not explanation:
- ❌ Step-by-step lessons (those are Tutorials)
- ❌ Problem-solving recipes (those are How-To)
- ❌ Technical specifications (those are Reference)
