Are you using SuperSocket 1.5? If yes, the 1.5 documentation should be helpful, https://github.com/kerryjiang/SuperSocket/wiki, but it's under working.
Anyway, you must take a look at the code in QuickStart.
If you are using SuperSocket 1.4, but please still use 1.4 except you are preparing to upgrade to 1.5 because 1.5 breaks many APIs of 1.4.
You can see there is an documentation in the doc list with the title "Upgrade from SuperSocket 1.4", but it's not finished.
I'll try my best to finish all the content of the documents before next 1.5 beta release, I aslo will have an copy of these documents in Codeplex project website.
