The book is written in Chinese. English repository guidance helps contributors; a complete English book is not available. Start with the preface and Part 1, install Racket/DrRacket as the chapters explain, then run small examples before moving on.
The book is free and needs no account. Chapters are educational material, not a promise that every example works on every Racket version, OS or hardware. Record your actual environment and compare errors with the chapter’s assumptions.
Reading the static book does not require uploading code. The feedback widget opens a prefilled public GitHub issue; review selected text and the full report before submitting. External links and embedded third-party resources have their own data policies.
Use the page feedback entry or Issues, including chapter URL, selected passage, Racket version, OS and a minimal example. Avoid secrets and private project source. Keep your exercises in a separate backed-up project; browser history is not a backup. Contributors use the lockfile, content checks and static build before publication.
Book text is CC BY-NC-SA 4.0; code examples have the additional MIT permission in LICENSE-CODE. These are different grants; the whole book is not MIT.
