+Many forms, such as questionnaires, can be very similar to one another in format and intent.
 To make it faster and easier to generate different versions of such a form,
 you can create a *dynamic form template* based on metadata that describes the business object model.
 Then, use the template to generate new forms automatically, according to changes in the data model.
 
 The technique is particularly useful when you have a type of form whose content must
 change frequently to meet rapidly changing business and regulatory requirements.

+   This tutorial shows how to build a questionnaire, which is just one kind of dynamic form.
    The example uses `FormGroup` to collect a set of controls.
    For an example of a different type of dynamic form, see the section [Creating dynamic forms](guide/reactive-forms#creating-dynamic-forms "Create dynamic forms with arrays") in the Reactive Forms guide.
    That example also shows how to use `FormArray` instead of `FormGroup` to collect a set of controls.
