How toLearn

Complete BeginnersFollow Stage 1 sequentially, every concept comes with hands-on practice, complete in 1-2 weeks
Used CodeWhale BeforeSkip Stage 1, dive into Stage 3 Skills/MCP/Memory directly
See the HighlightsJump to Stage 4 for Thinking visualization + Sub-agent parallelism — the core differentiator of this course
Just Looking Things UpEach module has reference cards and command cheatsheets, look up as needed

PrerequisitesPrerequisites

✓Can use command-line terminal
✓Basic Git operations (clone, commit, push)
✓Understand basic syntax of at least one programming language
✓Have a DeepSeek account (free to register)
△Node.js project experience is a plus
△Understand TOML config file format

✓ Required | △ Bonus, can learn without

LearningPrinciples

  1. Cost Advantage — CodeWhale's core advantage is 1/10 cost, experience first then go deeper
  2. Hands-on — not a forget-after-watching tutorial
  3. Transparent Thinking — watch AI think in real time and understand why it does what it does
  4. Progressive Config — use existing configs first, adjust as needed
  5. Automation Flow — learn to create your own automation workflows
  6. Zero Install — start practicing without installing anything
