The "Instances" functionality from the "jHQ" submenu in the "Administration" menu is used to define jHQ queuing system instances. Essentially, the jHQ system instance is related to its location (eg queuing system in a specific unit). After selecting this functionality, a list of the queuing system instances is displayed and the "Edit" and "Delete" buttons are displayed for each of them. Below the list of instances, the "Add" button is displayed.

To add a new instance, click "Add" button. The form for adding an instance will be displayed, where you should enter its name and click "Add" button.

After clicking the "Add" button, the system will automatically switch to the instance editing mode with sections to be entered

• types of printed tickets (eg registration for BHC, specialist registration, registration for children, ...)
• registration posts from which tickets will be called
• printers that will be used to print tickets

Each of the above sections is organized in a similar way: the green "+" button allows you to add a new item to the section: type of tickets/position/printer, red "×" button allows you to remove the element: type of tickets/position/printer at which it is located. To add a new type of tickets / position/printer, click the green "+" button in the appropriate section. Then the system will display windows, asking step by step for entering the new item data. In the case of ticket types, the ticket number of a given type is created by concatenating the prefix (entered in the "Number prefix" field) with the subsequent ticket number (automatically generated) completed with zeros to the specified number of digits (indicated in the "Number of digits" field) and ticket numbering starts again from day to day at the time specified in the field "Reset number time" (if the time is not given, then the numbering of tickets will be continuous, continuing each day with the numbering from the previous day). You can manually reset the ticket numbering at any time by clicking the blue "0" button on the ticket type and confirming your intention to reset. In the case of posts, the type of tickets called from a given post is indicated. In the case of printers, an interface is defined which indicates the mechanism of communication with the printer and indicates the types of tickets that will be printed on a given printer. In addition to adding and removing types of tickets/posts/printers, their data visible on the form can be modified and the modifications confirmed with the "Update" button.

To modify the details of the queuing system instance, click the "Edit" button for the given instance in the list. The instance edit form with its data will be displayed. You can make changes to the form as described in the previous paragraph. The changes should be saved by clicking the "Save" button.

To delete an instance, click the "Delete" button for the given instance in the list. The form with the instance data is then displayed in read-only mode. The intention to delete an instance should be confirmed by clicking the "Delete" button.
