Yes. For new authors, there’s a fully guided online training at https://websense.stanford.edu/ (required for new users, optional for existing). This updated course necessitates access to a training sandbox to practice exercises in the new interface. To gain access to this sandbox, please make a request. Note the content is biased towards a new user, so it may be redundant for experienced authors and is not required for existing authors.
For existing authors, there's abbreviated content within the Touch Transition site including a video overview, quick reference, and component encyclopedia.
