A few things worth knowing.

Each guide contains written explanations, annotated Ruby examples, exercises and suggested approaches. The product page lists its specific modules. Separate source-code downloads are not included unless explicitly stated.

There is no fixed timetable. Each product page gives an estimated reading and practice time; your pace and prior knowledge will affect the time you need.

The material is delivered as downloadable PDF guides in English. Video, audio and live lessons are not included.

Free Kit and Echo Pack start with the basics. Later guides assume the knowledge listed under “Who it is for” on each product page.

You may keep your downloaded copy for personal study without a subscription or scheduled expiry. Keep a backup; indefinite hosting of download links is not promised.

There is no fixed update schedule. Published revisions will be described on the Latest updates page. Future editions are not automatically included unless stated.
