Cookbook vs Tutorials

Cookbook:

• Problem → Solution format
• Assumes basic knowledge
• Quick reference
• Copy-paste ready

Tutorials:

• Concept → Example format
• Teaches from basics
• Progressive learning
• Explanatory focus

Use both together: Tutorials for understanding, Cookbook for application.
