There is a excellent video training (about 2 hours) how you can use Explaindio 4.0 for the best results. This training isn’t a part of the program or an upsell. It’s a stand-alone product made by Scott Hamlin and called Explaindio For Professionals ($27.00). I can highly recommend this quality training. It’ll save you time and many and fore all give you great ideas and examples how to use the software without any prior experience.
