What is Tour ?
Drupal 9.2 has introduced a new tour framework replacing Joyride with Shepherd .
Since Drupal 8 there Tour module is in core. It is very useful when you need to guide user within your application. We use it In EK management tools targeted at users with small to medium scale companies. They usually have limited resources and time to spend on back office trainings. This is where the Tour module is very convenient to introduce functionalities to users who can quickly grasp the functions available to manage their back office.
You can try the latest version of Tour with the demo application where many of the forms and pages have a tour guide for users.
