If you want to dive deeper into the full range of what our widgets can do and are comfortable with code, we suggest you visit https://www.rsvp-popup.com/docs.
The docs you find there will be updated as any changes to the widget are made.
Otherwise, for a simpler introduction, visit the other help articles we have created in the Developer Tips section of the Help Center.
If you still have questions, drop us a line at support@rsvp-popup.com.
