Networking Basics

Hello there. I would like to ask you, if you know some youtuber or blog or website, where can I learn Unity Networking from scratch? I’m not really comfortable with uNet, as I was watching official videos and so… I was also checking the answers, found some resources but most of them are too old or aren’t availible at all…

I have some experiences with Unity3D, but none with Networking and my first goal is to create a simple chat… So, where should I start? Thanks for help.

I’d start with YouTube
