User Education in Chrome is designed to introduce users to new and existing features with which they might not be familiar.
The user education system provides a common UX for nudging users towards these features, including full, user-initiated tutorials.
User education experiences should start at the UX design and PRD stage of feature design, as they are integral parts of any major new feature. UX and PM should refer to the Desktop User Education Homepage for guidance long before any implementation work begins.
When you are ready to implement your feature's user education journey, begin with the Getting Started Guide.
