Hi,
SFS1.x and SFS2X are very similar in the ways they work. We have maintained the same logic and basic concepts (Zones, Rooms, Users, Server Variables etc...) plus added lots of new features.
The only thing that changes significantly is Extensions, which are more "structured" than SFS1.x
You can start with the documentation here:
http://docs2x.smartfoxserver.com/Gettin ... stallation
And also download the examples for the client platform you're working with:
https://www.smartfoxserver.com/download#p=examples
You'll find the relative tutorials in the docs website as well.
Cheers
