The Tour module allows you you make instructional tours of user interfaces.
The Tour module comes with Drupal 8 and makes it easy for developers to add "Tours" for guiding users through unfamiliar user interfaces.
Each tour is comprised of a series of tooltips that provide contextual information about an interface. The user can start a tour by clicking the "Tour" icon on the right side of the Drupal 8 toolbar. The tour icon is only visible when there is a tour available on the current page.
The Tour module provides the Tour API, which makes it easy for developers to add tours to their modules. In most cases, adding a tour is as simple as creating a YAML file in the config directory in their module, containing the expected data. For a detailed example of such a file, see config/install/tour.tour.tour-example.yml.
If you are interested in building tours through a user interface, you may want to look at the Tour UI module: https://drupal.org/project/tour_ui
The Tour module uses the Joyride jQuery plugin for its underlying functionality. You can find more information about Joyride at https://github.com/zurb/joyride
