Hi,

General instructions and code examples can be found in our Integration Guide

Up to which level do you want to integrate the systems, could you please describe your aim in more details?
Do you want to synchronize complete forms or just some parts (some specific Salesforce info)? Should the sync be bi-directional?
Any further details would be helpful. You can also contact us via email at support@kentico.com.

Regards,
Zdenek
