Is there any MERN tutorial for dummies?

I'm glad to find you guys, i had to make a work for crossover.com with MEAN stack and i really found horrible Angular2, so complicated, then i found React, looks better, then i found you MERN and i like the idea... But, guys my question goes here... Is there any MERN tutorial for dummies ?? I really need it because i want to understand the structure, arquitecture, and of course more of reactjs but with mern. I have more clear server side, but the client one , oh god! i am heaving a headchache and i feel frustrated.
