Within the modules screen of a page drag the registration module box into the placeholder.
There are several options here. Tick the boxes next to the fields you wish to display on the form and select whether they are mandatory. There are also options to add introductory text to each section of the form.
Towards the bottom there are options to add thank you text once the user has filled out the form as well as data protection information.
To add the registration module click on save in the top right corner or cancel to discard any changes.
The module will then be shown. You can then click on publish in the top right corner.
