S4S for Sitecore 9 and Later
The core S4S functionality (the integration engine we call G4S) is remains largely unchanged however the out-of-the-box S4S functionality like web form and analytics support have been significantly upgraded. This was required due to the changes Sitecore made to xDB.
Continue on this path only if you have Sitecore 9 or a later version. If you have a version earlier than Sitecore 9 please follow this process.
