## Short answer
Start with a small real task, let Claude Code inspect the repo, ask for a plan, review the diff, and run tests. That teaches the workflow better than a toy app demo.

## Context from the full guide
Start with the DeepLearning.AI Claude Code course or Peter Yang's beginner tutorial, then use Anthropic docs and real-world feature-build walkthroughs to learn planning, editing, testing, and review habits.
