After you enable the “People” module, you will find the People subtab (2) inside the plugin’s Configuration tab.
In this section, you can create unlimited “people types”: for each type you only need to enter the name and, optionally, a short description (3).
Click on the “Add new type” button to save the “people type” and see it in the table.
Now you can configure people for every bookable product. Read the “How to create a bookable product” section for reference.
